EXPERIMENTAL STUDY ON RESIDUAL AXIAL LOAD CAPACITY OF R/C COLUMNS FAILING IN SHEAR
In order to avoid pancake type collapse of existing old R/C buildings during severe earthquakes, it is necessary to evaluate residual axial load capacity of existing R/C columns. This residual axial load capacity is defined as axial load carrying capacity of a column after the column suffers serious damage, which corresponds to the safety limit state. On the other hand Standard for evaluating method of seismic performances of existing R/C buildings, which is popularly used in Japan, shows evaluating methods of residual axial load capacities, which have dramatic effects on seismic performance indexes. Objectives of this study are to examine the residual axial load carrying capacity of R/C columns after shear failure. We pay special attention to confining effects of hoop reinforcement depending on their reinforcing details.
