- Abstract
- A computer-aided design procedure based on limit state design concepts is proposed for multistory reinforced concrete frames of buildings which are expected to experience severe earthquake ground shaking during their service life. In this procedure a structure is designed to meet (1) various serviceability criteria under service loading conditions, (2) damage limitations for abnormal environmental conditions, and (3) safety requirements for extreme earthquake excitations. The design procedure, which makes use of computer optimization methods as well as static and dynamic elastic and nonlinear analysis procedures, consists in five basic steps which are grouped into a preliminary design phase and a final design phase. The objective of the preliminary design phase is to obtain a preliminary design which is as close as possible to the desired final design. It entails three steps, preliminary analysis, preliminary design, and analysis of the preliminary design.
