Multi-Story Tilt-Up Wall Design Spreadsheet

Multi-Story Tilt-Up Wall Design Spreadsheet



Tilt-Up construction is continuing to grow at a record pace. Over the past three years, about one billion square feet of Tilt-Up wall panels have been constructed to provide approximately 2.3 billion square feet of usable floor space. While a significant percentage of this growth has come from single-story building construction, the multi-story Tilt-Up market has really begun to flourish. The design of these multi-story Tilt-Up buildings is significantly more involved than that of single-story buildings.

Multi-story tilt-up wall design is challenging compared with one-span (single-story) tilt-up wall. Selecting wall
thickness is different than the typical single-story application, and can result in a much thinner section. Thus,
stresses during construction and lifting should be investigated for the influence on required vertical reinforcement.
The reference example examines the reinforcement required for the final in-service condition only.

Coagulation and Flocculation in Water and Wastewater Treatment

Coagulation and Flocculation in Water and Wastewater Treatment 

John Bratby

Preference :

Coagulation and flocculation are essential processes in a number of diverse disciplines, including biochemistry, cheese manufacturing, rubber manufacturing, and in water and wastewater treatment. Many people are probably familiar with the general concept of coagulation from the well known chemically caused clotting of blood when exposed to air. Another well known example of coagulation is the hard-boiling of an egg, in which the protein coagulates and hardens by heat. In water and wastewater treatment, coagulation and flocculation phenomena are extremely important. In the area of potable water treatment, clarification of water with coagulating agents has been practiced from ancient times, using a variety of substances – most notably crushed seeds. The Egyptians as early as 2000 BC used almonds smeared around a vessel to clarify river water. Flocculation was achieved by plunging an arm into the vessel. The early Romans were also familiar with alum, although perhaps not for water treatment. However, its use as a coagulant by the Romans was mentioned in ca. 77 AD. By 1757, alum was used for coagulation in water treatment in England, and more formally for the treatment of public water supplies in 1881 (Faust & Aly, 1998). In modern water treatment, coagulation and flocculation are still essential components of the overall suite of treatment processes. From an engineering survey of the quality of water treatment at over twenty operating water treatment plants, Cleasby et al. (1989) concluded: Chemical pretreatment prior to filtration is more critical to success than the physical facilities at the plant.

Principles of Thermodynamics

Principles of Thermodynamics 

JEAN-PHILIPPE ANSERMET

Preference :

Thermodynamics is a theory that establishes the relationship between the physical quantities that characterize the macroscopic properties of a system. In this textbook, thermodynamics is presented as a physical theory which is based upon two fundamental laws pertaining to energy and entropy, which can be applied to many different systems in chemistry and physics, including transport phenomena. By asserting that energy and entropy are state functions, we eliminate the need to master the physical significance of differentials. Thus, thermodynamics becomes accessible to anyone with an elementary mathematical background. As the notion of entropy is introduced early on, it is readily possible to analyze out-of-equilibrium processes taking place in systems composed of simple blocks. Students engaging with thermodynamics have the opportunity to discover a broad range of phenomena. However, they are faced with a challenge. Unlike Newtonian mechanics where forces are the cause of acceleration, the mathematical formalism of thermodynamics does not present an explicit link between cause and effect. Nowadays, it is customary to introduce temperature by referring to molecular agitation and entropy by invoking Boltzmann’s formula. However, in this book, the intrusion of notions of statistical physics are deliberately avoided.

 It is important to start off by teaching students the meaning of a physical theory and to show them clearly the very large preliminary conceptual work that establishes the notions and presuppositions of this theory. Punctual references to notions of statistical physics, which are not formally presented, give the impression that in science the results from another theoretical body of knowledge can be borrowed without precaution. By doing so, students might not perceive thermodynamics as a genuine scientific approach. It is clear that the introduction of entropy with a mathematical formula is somewhat reassuring. However, it is by performing calculations of entropy changes in simple thermal processes that students become familiar with this notion and not by contemplating a formula that is not used in the framework of thermodynamics.

Electric Motor Control

Electric Motor Control 

Sang-Hoon Kim

Preference :

Owing to rapidly increasing energy costs and global interest in reducing carbon dioxide emissions, electric motors have recently become one of the most important prime movers that produce mechanical power. Recently, in many mechanical systems, traditional prime movers such as a hydraulic system, a steam turbine, a gas turbine, and an internal combustion engine are being rapidly replaced by electric motor drive systems, which are more efficient, controllable, and environment friendly. Currently, electric motor drive systems are playing an important role in improving convenience in many areas of our lives including home appliances, office machines, transportation, and industrial machines. The main aim of this book is to introduce practical drive techniques of electric motors for supporting stable, efficient control of such application systems, covering basic principles to high-performance motor control techniques. Nowadays, the most widely used motors are classic direct current (DC) and alternating current (AC) motors (induction motor and synchronous motor). Besides these motors, there is a brand new brushless direct current (BLDC) motor. To control these motors efficiently, we will do a comprehensive study of fundamental operating principles, driving methods of electric motors, related control theories, and power converters for driving a motor. Many people do not have the background knowledge in these areas and may need to obtain these contents from various books. Therefore, this book is designed optimally for studying these contents at once and easy learning of difficult control principles. Furthermore, this book provides simulation examples for key subjects using MATLAB/ Simulink tool and offers practical control techniques for industrial motor drive applications currently in use.

Rectangular Concrete Beam Analysis And Design Spreadsheet

Rectangular Concrete Beam Analysis And Design



"RECTBEAM" is a spreadsheet program written in MS-Excel for the purpose of analysis/design of rectangular beam or column sections.  Specifically, the ultimate moment capacity, bar spacing for crack control, moments of inertia for deflection, beam shear and torsion requirements, and member capacity for flexure (uniaxial and biaxial) with axial load are calculated.  There is also a worksheet which 
contains reinforcing bar data tables. This version is based on the ACI 318-11 Code.
This program utilizes the following references: a. "Design of Reinforced Concrete" (Ninth Edition) (for ACI 318-11), by Jack C. McCormac & Russell H. Brown b. "Notes of the ACI 318-11 Building Code Requirements for Structural Concrete" (Twelfth Edition), by PCA 3.  The "Complete Analysis" worksheet combines the analyses performed by four (4) of the individual worksheets all into one.  This includes member flexural moment capacity, as well as shear, crack control, and inertia calculations.  Thus, any items below pertaining to any of the similar individual worksheets included in this one are also applicable here. 4.  In the "Flexure", "Uniaxial", and "Biaxial" worksheets, when the calculated distance to the neutral axis, 'c', is less than the distance to the reinforcement nearest the compression face, the program will ignore that reinforcing and calculate the ultimate moment capacity based on an assumed singly-reinforced section. 5.  In the "Uniaxial" and "Biaxial" worksheets, the CRSI "Universal Column Formulas" are used by this program to determine Points #1 through #7 of the 10 point interaction curve.  For the most part, these formulas yield close, yet approximate results.  However, these results should be accurate enough for most applications and situations.

Road Traffic Congestion: A Concise Guide

Principles of Foundation Engineering, Ninth Edition 

John C. Falcocchio, Herbert S. Levinson

Preference :

Congestion in transportation facilities—walkways, stairways, roads, busways, railways, etc.—happens when demand for their use exceeds their capacity. Travelers tend to complain about traffic congestion because it adds to their travel time and takes away from the time they can dedicate to other activities. Truck drivers complain because it reduces their productivity and increases their operating costs. Transit service providers complain about roadway traffic congestion because it increases the number of buses and drivers needed to provide the service. Congestion increases business costs, air pollutant emissions and fuel consumed. Congestion also can influence investment decisions, and therefore it becomes a major economic concern. It influences where people live, work and how they travel. Therefore reducing congestion benefits a wide constituency. Traffic congestion has been a fact of city life from ancient times when movement was by walking and animal-drawn coaches to today’s cities that rely on various means of mechanized travel. It is a byproduct of economic activities that grow faster than the growth in transportation infrastructure. Traffic congestion is now found in cities throughout the world. It continues to increase as the cities’ population and motorization grow and as travel growth outpaces investments in roads and public transportation. The beginning of congestion is generally perceived by drivers when their trip time increases by approximately 0.4–0.5 min/mile, and they become acutely aware of congestion when it increases by 0.8–1.0 min/mile. Traffic congestion may also be the hallmark of a vibrant economy: a city without a traffic congestion problem is likely to experience an economic recession, or a declining population. But where congestion is too pervasive and trip time reliability is a problem, the city may become a less desirable attraction for economic growth.

Principles of Foundation Engineering, Ninth Edition

Principles of Foundation Engineering, Ninth Edition 

Braja M. Das

Preference :

Geotechnical engineering, also known as geomechanics, is an emerging area in civil engineering. It deals with soil mechanics, with some emphasis on rock mechanics, where we apply engineering principles, such as the theory of elasticity, Mohr’s circle, and continuum mechanics, to develop simple solutions that can be applied to geotechnical and foundation engineering problems. When dealing with problems related to geomaterials, which include soil, aggregates, and rocks, some knowledge of geology is always an advantage. A thorough understanding of the geotechnical engineering fundamentals is a prerequisite for studying foundation engineering. These include phase relations, soil classification, compaction, permeability, seepage, consolidation, shear strength, slope stability, and soil exploration. These areas are covered in Principles of Geotechnical Engineering (9th Edition) in good detail. The main points are discussed very briefly in Chapters 2 and 3 in Part 1 of this text. A new chapter on geotechnical instrumentation is included in this edition as Chapter 4 in Part 1. When projects become complex or the design or construction methods are nonstandard, it is often advisable to use instruments and measure the loads, stresses, deformations, and strains at critical locations and monitor them over a certain period to ensure the performance of the structure is satisfactory. This new chapter gives an overview of the major instruments used in geotechnical engineering.

Mechatronics: Electronic Control Systems in Mechanical and Electrical Engineering

Mechatronics: Electronic Control Systems in Mechanical and Electrical Engineering

William Bolton

Preference :

The term mechatronics was ‘invented’ by a Japanese engineer in 1969, as a combination of ‘mecha’ from mechanisms and ‘tronics’ from electronics. The word now has a wider meaning, being used to describe a philosophy in engineering technology in which there is a co-ordinated, and concurrently developed, integration of mechanical engineering with electronics and intelligent computer control in the design and manufacture of products and processes. As a result, mechatronic products have many mechanical functions replaced with electronic ones. This results in much greater flexibility, easy redesign and reprogramming, and the ability to carry out automated data collection and reporting. A mechatronic system is not just a marriage of electrical and mechanical systems and is more than just a control system; it is a complete integration of all of them in which there is a concurrent approach to the design. In the design of cars, robots, machine tools, washing machines, cameras and very many other machines, such an integrated and interdisciplinary approach to engineering design is increasingly being adopted. The integration across the traditional boundaries of mechanical engineering, electrical engineering, electronics and control engineering has to occur at the earliest stages of the design process if cheaper, more reliable, more flexible systems are to be developed. Mechatronics has to involve a concurrent approach to these disciplines rather than a sequential approach of developing, say, a mechanical system, then designing the electrical part and the microprocessor part. 
Thus mechatronics is a design philosophy, an integrating approach to engineering. Mechatronics brings together areas of technology involving sensors and measurement systems, drive and actuation systems, and microprocessor systems ( Figure 1.1 ), together with the analysis of the behaviour of systems and control systems. That essentially is a summary of this book. This chapter is an introduction to the topic, developing some of the basic concepts in order to give a framework for the rest of the book in which the details will be developed.

Post Tensioned Analysis & Design Spreadsheet

Post Tensioned Analysis & Design Spreadsheet



 Post-tensioning tendons, which are prestressing steel cables inside plastic ducts or sleeves, are positioned in the forms before the concrete is placed. Afterward, once the concrete has gained strength but before the service loads are applied, the cables are pulled tight, or tensioned, and anchored against the outer edges of the concrete.

Post-tensioning is a form of prestressing. Prestressing simply means that the steel is stressed (pulled or tensioned) before the concrete has to support the service loads. Most precast, prestressed concrete is actually pre-tensioned-the steel is pulled before the concrete is poured. Post-tensioned concrete means that the concrete is poured and then the tension is applied-but it is still stressed before the loads are applied so it is still prestressed.

This spreadsheet provides the user with a fundamental understanding of post-tensioned concrete design to enable the use of a spreadsheet program. The program provides for the ultimate strength and service stress design and analysis of one-way beam and slab and two-way flat plate systems.

Building Design and Construction Handbook, 6th Edition

Building Design and Construction Handbook, 6th Edition

Frederick S. Merritt

Preference :

The sixth edition of the Building Design and Construction Handbook maintains the original objectives of previous editions which gained widespread acceptance among users. These objectives are to provide in a single volume a compendium of the best of the current knowledge and practices in building design and construction. This information would be of greatest use to those who have to make decisions affecting the selection of engineering materials and construction methods. Emphasis is placed on fundamental principles and practical applications, with special attention to simplified procedures. Frequent reference is made to other sources where additional authoritative information may be obtained, such as architectural and engineering societies, manufacturers associations, and the Internet. An extensive index is provided to assist the reader in locating topics within the book. Many new contributors and sections have been added in this edition to provide the reader with the latest developments and knowledge in the building industry. These developments include the expansion of data technology and communication systems within the building system, revisions to wind and seismic loadings, and an expansion of the information on fire sprinkler systems. To present the necessary information in a single volume, obsolete and less-important information in the earlier editions has been deleted. The editor is very grateful to the contributors, not only for their care, skill, and knowledge used in preparing the sections, but also for their considerable sacrifices of personal time to prepare the sections.

Sociological changes, new technology in industry and commerce, new building codes, other new laws and regulations, inflationary economies of nations, and advances in building technology place an ever-increasing burden on building designers and constructors. They need more and more knowledge and skill to cope with the demands placed on them. The public continually demands more complex buildings than in the past. They must serve more purposes, last longer, and require less maintenance and repair. As in the past, they must look attractive. Yet, both building construction and operating costs must be kept within acceptable limits or new construction will cease. To meet this challenge successfully, continual improvements in building design and construction must be made. Building designers and constructors should be alert to these advances and learn how to apply them skillfully.

How Structures Work: Design and Behaviour from Bridges to Buildings

How Structures Work: Design and Behaviour from Bridges to Buildings

David Yeomans

Preference :

The dedication of this book requires some explanation because, although it has been written to be suitable for architectural students, it was not originally conceived as such. The dedicatees include two archaeologists and an antiquarian book dealer. The idea for the book goes back further than I care to remember. Visiting an archaeologist friend, I picked up a book on Greek architecture, and it became apparent that the author’s understanding of structure and construction lacked something. ‘Don’t you think, Louise, that it would be a good idea for archaeologists to learn something about building structures?’ ‘Yes it would’ – and so the seed was sown. The idea was simply that something on building structures might be useful for people with little or no mathematics but whose work or subject of study involves understanding buildings. Many years later, Jane Grenville asked me if I could give some classes to her master’s course on buildings archaeology at York University. ‘Structures for archaeologists? I’ve always wanted to try teaching that’. And so the text for this began with the notes for that class. Working up the text into this form was pushed aside by other things until Julia, a dealer in antiquarian engineering books, said that she had asked the late Professor Skempton if he could teach her some structures. He’d claimed it would be difficult because the subject is highly mathematical. She thought this nonsense, pointing out that she frequently heard engineers discussing structures but they never used any mathematics. Of course, she’s right; we seldom do when thinking about structures. The general experience is that one manages with a few simple concepts. Given the rule for static equilibrium, the triangle of forces and some ideas about moments and elasticity, one has the basic bag of tools that will cope with most situations. What one needs to add to this to make a designer, rather than a mere stress analyst, is an understanding of the properties of the materials that make up the structures we build, because no real understanding is possible without that. How then to provide the simple bag of tools? Goaded by Julia’s demands, I determined to tackle the problem.

Pile Cap Design Excel Sheet

Pile Cap Design Excel Sheet



A pile cap is a thick concrete mat that rests on concrete or timber piles that have been driven into soft or unstable ground to provide a suitable stable foundation. It usually forms part of the foundation of a building, typically a multi-story building, structure or support base for heavy equipment. The cast concrete pile cap distributes the load of the building into the piles. A similar structure to a pile cap is a “raft”, which is a concrete foundation floor resting directly onto soft soil which may be liable to subsidence.

Short-Circuit Currents (Power & Energy)

Short-Circuit Currents (Power & Energy)

Jurgen Schlabach

Preference :

Electrical power systems have to be planned, projected, constructed, commissioned and operated in such a way to enable a safe, reliable and economic supply of the load. The knowledge of the loading of the equipment at the time of commissioning and as foreseeable in the future is necessary for the design and determination of the rating of the individual equipment and of the power system as a whole. Faults, i.e., short-circuits in the power system cannot be avoided despite careful planning and design, good maintenance and thorough operation of the system. This implies influences from outside the system, such as short-circuits following lightning strokes into phase-conductors of overhead lines and damages of cables due to earth construction works as well as internal faults, e.g., due to ageing of insulation materials.

Switchgear and fuses have to switch-off short-circuit currents in short time and in a safe way; switches and breakers have to be designed to allow even switch-on to an existing short-circuit followed by the normal switch-off operation. Short-circuit currents flowing through earth can induce impermissible voltages in neighbouring metallic pipelines, communication and power circuits. Unsymmetrical short-circuits cause displacement of the voltage neutral-to-earth and are one of the dominating criteria for the design of neutral handling. Short-circuits stimulate mechanical oscillations of generator units which will lead to oscillations of active and reactive power as well, thus causing problems of stability of the power transfer which can finally result in system black-out. Furthermore, equipment and installations must withstand the expected thermal and electromagnetic (mechanical) effects of short-circuit currents.

Project Management in Construction

Project Management in Construction

Project Management in Construction

Sidney Levy

Preference :

The importance of the project manager's role in the construction process cannot be overstated. From the two-dimensional plans and specifications that mark the first step of the building process to the ribbon-cutting ceremony at project completion, the project manager is a key player. The path from Point A to Point B is rarely without its detours and roadblocks and the project manager is charged with the responsibility of traversing those detours and tearing down the impasses. A project manager must be technically competent and possess the management skills necessary to effectively control the teams of subcontractors, vendors, and field personnel required to provide the smooth flow of tradespeople and materials needed to get the job done. A little knowledge of accounting procedures, legal matters, and state and federal regulations is also best in order to effectively deal with the many forces that bear on the construction process. Part-time instructor, father confessor, disciplinarian, and mediator, one thing is for sure, a project manager's daily routine is never the same. Only change is constant.

In the end, project management is an exercise in control: control over quality, schedule, and costs-each one a full-time job, yet all falling under the aegis of the project manager. Project Management in Construction, now in its Fifth Edition, examines some of the basic tenets of managing a construction project and explores new technologies that will impact how we do business in the future.

Principles of Foundation Engineering, Eighth Edition

Principles of Foundation Engineering, Eighth Edition

Braja M. Das

Preference :

In the general sense of engineering, soil is defined as the uncemented aggregate of mineral grains and decayed organic matter (solid particles) along with the liquid and gas that occupy the empty spaces between the solid particles. Soil is used as a construction material in various civil engineering projects, and it supports structural foundations. Thus, civil engineers must study the properties of soil, such as its origin, grain-size distribution, ability to drain water, compressibility, shear strength, loadbearing capacity, and so on. Soil mechanics is the branch of science that deals with the study of the physical properties of soil and the behavior of soil masses subjected to various types of forces. Rock mechanics is a branch of science that deals with the study of the properties of rocks. It includes the effect of the network of fissures and pores on the nonlinear stressstrain behavior of rocks as strength anisotropy. Rock mechanics (as we know now) slowly grew out of soil mechanics. So, collectively, soil mechanics and rock mechanics are generaly referred to as geotechnical engineering.

Foundation engineering is the application and practice of the fundamental principles of
soil mechanics and rock mechanics (i.e., geotechnical engineering) in the design of foundations
of various structures. These foundations include those of columns and walls of
buildings, bridge abutments, embankments, and others. It also involves the analysis and
design of earth-retaining structures such as retaining walls, sheet pile walls, and braced
cuts. This text is prepared, in general, to elaborate upon the foundation engineering aspects
of these structures.

Gravity Sanitary Sewer Design and Construction

Gravity Sanitary Sewer Design and Construction

Paul Bizier

Preference :

Wastewater treatment and collection systems are a major expenditure of public funds, but the wastewater system’s function is rarely acknowledged and sewers are seldom seen by the public. Sanitary systems are essential to protecting the public health and welfare in all areas of concentrated population and development. Every community produces wastewater of domestic, commercial, and industrial origin. Sanitary sewers perform the vitally needed functions of collecting these wastewaters and conveying them to points of treatment and disposal. The various stages of design and construction of sanitary sewer projects require an understanding of the objectives of each stage of the project and of the responsibilities and interests of the parties involved. Separate sanitary and storm sewers are highly desirable and are used, with few exceptions, in new systems. The major advantages of separate systems, including wastewater treatment plants, are the protection of watercourses from pollution and the exclusion of stormwater from the treatment system with a consequent saving in treatment plant construction and operating cost. Combined sewers are frequently encountered in older communities where it may be extremely difficult or costly to provide separate systems. Separation is desired, where economically feasible, to reduce the magnitude of facilities and energy demand of treatment works.
