Abstract

Main purpose of this study is to investigate residual seismic capacity of damaged buildings. An evaluation method of residual seismic capacity (R) using contribution factors of structural components (Er) was proposed. Er is evaluated by assuming invariable inter-story drift distribution for a building even after damage to focus on the investigation of effect of location of components. Then, modeling methods of damaged buildings were discussed using SDOF models. Finally it was shown that the proposed method can estimate R appropriately for buildings with uniform inter-story drift distribution but cannot for buildings with non-uniform distribution through dynamic analyses of prototype frames.
