| This paper aims to provide an analysis method for simulating the seismic behavior of a RC pier under multi-directional seismic excitation. Three-dimensional elasto-plastic finite element method was adopted with a purpose to make it possible to consider the failure mode of flexure-shear failure at the termination location of the main rebar. Two RC pier specimens, in which one failed in flexure failure at the base of the pier and the other failed in flexure-shear failure at the main rebar termination location, were analyzed and the validity of the analysis method was discussed. Discussion results show that the analyses provided a successful identification of the failure mode and a good simulation of the seismic behavior before the effect of concrete cover spalling over the responses become dominant. |
