Abstract: An optimization method is presented for long-span frames for specified seismic responses considering spatial variation of ground motions. The response is evaluated by using a response spectrum approach, where incoherency ...

Abstract: Properties of Pareto optimal solutions considering bounded uncertainty are first investigated using an illustrative example of a simple truss. It is shown that the nominal values of the Pareto ...

Abstract: The purpose of this paper is to show that the performance of a structural component is drastically improved utilizing shape optimization considering inelastic responses. Optimal flange shapes are found as an example for ...

Abstract: The time-variant system reliability analysis is a challenging and significant topic, which also faces the common obstacles of traditional system reliability methods such as combination explosion and unclear correlation ...
