Abstract

Main purpose of this study is to investigate residual seismic capacity of damaged buildings. An evaluation method of residual seismic capacity (R-index) using contribution factors of structural components (Er) was proposed. In this method, Er is evaluated based on strength, displacement and energy dissipation, whereas a contribution factor used in the current Japanese Post-earthquake Damage Evaluation Guideline is calculated only by strength. Then, modeling methods of damaged buildings were discussed using SDOF models. Finally, applicability of each method was discussed through dynamic analyses of beam-yielding RC frames with various inter-story drift distribution. In result, it was shown that the proposed method can estimate R-index appropriately for all kinds of buildings, whereas the current guideline method can only for buildings with uniform inter-story drift distribution.
