Evaluation on seismic response behavior for RC underground structure using 3D material nonlinear analysis

Abstract

The present paper assesses and discusses seismic performance of an underground reinforced (RC) structure. For this purpose, the authors applied a nonlinear three dimensional (3D) dynamic analysis and a pushover structural analysis to examine the effects of structural profile, input ground motion angle and cyclic static loading on global as well as local response properties of the target structures. As a result, the 3D analysis demonstrates that the wall well hinder global structural deformation even under the most critical input wave angle. In addition, the pushover analysis, which includes equivalent dynamic earth pressures, can provide approximately the same degrees of deformation with that of the 3D dynamic analysis if the cyclic static loading is considered.
