CHAPTER 4

GENERATING ET EXCITATION FUNCTIONS BY NUMERICAL OPTIMIZATION

4.1 INTRODUCTION

One of the major challenges in earthquake engineering is the numerical simulation of seismic structural response and there has been remarkable progress in developing appropriate software for this purpose in the last decade (Kaveh et al. 2010; Sajeeb, Roy, and Manohar 2007; Gholizadeh, Salajegheh, and Salajegheh 2009). Providing appropriate safety margin against structural failure in destructive earthquakes is one of the major objectives in the seismic design.1 There are different methods to analyze seismic performance of structures which can be selected according to design conditions and requirements. Equivalent static analysis, modal analysis, and dynamic ...
