Earthquake Effects

The chapter provides an overview of optimal structural design procedures for seismic performance. Structural analysis and design for earthquake effects is an evolving area of science; many design philosophies and concepts have been proposed, investigated, and practiced in the past three decades. The chapter briefly introduces some of these advancements first, as their understanding is essential in a successful application of optimal seismic design for performance. An emerging trend in seismic design for optimal performance is speculated next. Finally, a state-of-the-art application of evolutionary algorithms in probabilistic performance-based seismic design of steel moment frame buildings is described through an example. In order to follow the concepts of this chapter, the reader is assumed equipped with a basic knowledge of structural mechanics, dynamics of structures, and design optimizations.

FEMA-353, Recommended Specifications and Quality Assurance Guidelines for Steel Moment-Frame Construction for Seismic Applications, contains numerous provisions related to the materials, details, quality, and inspection of steel moment-frame buildings in seismic regions. These provisions continue to evolve as industry standards and practices are reviewed, modified, and adopted to meet the need for good seismic performance. Those writing project specifications must remain current with new industry developments and standards.

Residual Deformations

Buckling-Restrained Brace (BRB) consists of energy dissipative core and a strengthening tube to prevent buckling when subjected to compression. Under cyclic loading, BRB exhibits elastoplastic hysteretic behavior, which leads to certain amount of permanent displacement in the structure after medium to severe earthquake. Residual deformations can result in increased cost of repairing. An innovative BRB device called Self-centering Buckling-Restrained Braces (SC-BRB) is devised to control maximum and residual drift of steel moment frame buildings subjected earthquakes. The SC-BRB is composed of the BRB energy dissipating cores which are responsible for energy dissipation, and the self-centering system which makes BRB energy dissipating core return to its initial position upon completely unloading. By exploring the mechanism of SC-BRB, it is found that to ensure fully self-centering capacity, the self-centering bar should have sufficient elongation capacity as well as considerably large elastic modulus which could afford stiffness in real structures
