RC Element Analysis and Design Program

RC Element Analysis and Design Program

The theory and techniques relative to the design and
proportioning of concrete mixes, as well as the placing,
finishing, and curing of concrete, are outside the scope
of this book and are adequately discussed in many other
publications . Field testing, quality control, and inspec-
tion are also adequately covered elsewhere. This is not to
imply that these are of less importance in overall concrete
construction technology but only to reiterate that the objec-
tive of this book is to deal with the design and analysis of
reinforced concrete members.

The design and construction of reinforced concrete build-
ings is controlled by the Building Code Requirements for

Structural Concrete (ACI 318-11) of the American Concrete
Institute (ACI) [1]. The use of the term code in this text
refers to the ACI Code unless otherwise stipulated. The
code is revised, updated, and reissued on a 3-year cycle. The
code itself has no legal status. It has been incorporated into
the building codes of almost all states and municipalities
throughout the United States, however. When so incorpo-
rated, it has official sanction, becomes a legal document, and
is part of the law controlling reinforced concrete design and

construction in a particular area.

therefore, tensile reinforcement must be embedded
in the concrete to overcome this deficiency. In the United
States, this reinforcement is in the form of steel reinforcing
bars or welded wire reinforcing composed of steel wire. In
addition, reinforcing in the form of structural steel shapes,
steel pipe, steel tubing, and high-strength steel tendons is

permitted by the ACI Code.
