This study presents the seismic evaluation and prediction of post-retrofitted piloti-type reinforced concrete building with buckling-restrained braces (BRBs) under the successive earthquakes. For seismic assessment before and after retrofit of the BRBs, the fragility analysis is considered. The fragility relationships for the damaged building between ground shaking intensity and damage probability were derived under the successive earthquakes.
