Seismic Design of Steel Structures

Seismic Design of Steel Structures

Victor Gioncu, Federico Mazzolani

Preference :

This book, titled Seismic Design of Steel Structures, represents the natural conclusion of twenty years of common activity between Victor and myself, which was finalized to give a substantial contribution to seismic design in general and in particular to seismic-resistant steel structures. The
predicted passage from local to global behavior was developed by taking into account the output of the first and second volumes. The whole material has been divided into six chapters.

Chapter 1, “Failure of a Myth,” starts from the consideration that steel is usually considered an ideal material for seismic-resistant applications, but some accidents in the last decades of the twentieth century undermined this reputation. These cases are listed in the first chapter, and the main reasons
for the anomalous behavior of steel structures, due to exceptional situations connected both to a lack of knowledge and/or design errors, are clearly identified and explained case by case. The main recent investigations come from the lessons learned from these tragic events.

Chapter 2, “Steel against Earthquakes,” shows how to use steel to resist seismic actions together with the reasons for the excellent behavior of seismic-resistant steel structures in many applications around the world, demonstrating that good design principles generally lead to successful
results.

Chapter 3, “Challenges in Seismic Design,” is devoted to identifying the gap in knowledge on the effects of different types of earthquakes on structural behavior and also considers some important lessons to be learned. It provides a suitable relationship with the main output of the second volume,
Earthquake and Structural Engineering. A distinction is given between strong and low-to-moderate seismic regions also from the point of view of the methodological approach.

Chapter 4, “New Generation of Steel Structures,” represents the heart of the book, illustrating the most advanced seismic-resistant structural systems based on the use of steel. Starting from the systems that improve existing solutions, that is, EBF (eccentric braces), RBS (dog-bone), and BRB
(buckling restrained braces), new bracing systems have been analyzed based on the use of steel and aluminum panels in the form of full-bay, partial-bay, and bracing types. These innovative systems are also applied to the seismic upgrading of existing RC buildings. Finally, new connecting systems for
beam-to-column nodes, based on posttensioned energy-dissipating (PTED) connections, are also illustrated.
