APPLICATIONS OF MATERIAL DAMAGE INDICES TO NONLINEAR 2D SEISMIC FINITE ELEMENT ANALYSES OF RC STRUCTURES

Abstract

 Applicability of material damage indices has been evaluated for previous nonlinear two dimensional seismic finite element analyses of RC structures with surrounding soil, a railway pier damaged in Tokachi earthquake 2003 and a subway culvert structure damaged in Hanshin-Awaji great earthquake 1995. Then, by using the second invariant of deviatoric strain tensor and consume strain energy averaged over certain region, seismic damage processes of RC structures and/or members can be approximately explained, as well as static experiments whose applicability has been already evaluated.
