Abstract

Standard for evaluating method of seismic performances of existing R/C buildings revised in 2001 showed evaluating methods of residual axial load capacity and axial load capacity, which had dramatic effects on seismic performance indexes. In this study the feasibility of this method was discussed using experimental data. For this purpose static loading tests of R/C columns were conducted. Main variable was loading methods; i.e. monotonic eccentric axial loading, eccentric axial loading under constant lateral drift and normal reversed lateral loading under constant axial load. An evaluating method of residual axial load capacity was proposed and compared with the standard.
