Multiobjective Optimum Design of Seismic-resistant Structures

Abstract

The concepts of genetic algorithms, game theory, Pareto optimal set with/without constraints, and life-cycle cost are discussed. Based on them, new algorithms for multiobjective optimization are developed. As such, multiobjective optimization provides a designer with a systematic method for considering all the conflicting requirements inherent in an application. The sensitivity of cost function on structural probability failure and optimum solution indicates that multiobjective and multilevel optimization, along with life-cycle cost model based on actual earthquake casualties and building damages, are essential to determine target reliability and seismic building code performance.
