Seismic Design Practice for Steel Buildings

Abstract

To properly interpret seismic codes and their revisions, it is becoming increasingly important that the design engineer have an understanding of the basic theory behind seismic code provisions. This paper provides a brief treatment of the subject of seismic theory and design, particularly as it applies to structural steel. Much of the theory is condensed into simple terms more readily applied to the typical problems faced by busy design engineers. Specific seismic code provisions are discussed, to aid in their interpretation. The author has specifically addressed the situation of engineers designing for the earthquake problems and building codes of the State of California. No attempt has been made to cover conditions not applicable to California. However, it is hoped that the paper will prove helpful to any engineer involved in the seismic design of steel buildings.
