| Research Abstract |
Ductility Index and Residual Axial Load Capacities of shear columns were studied. The major findings from the study are as follows. 1. The analytical method to determine Ductility Index was proposed, which would lead to its more reasonable evaluation. 2. The analytical method to determine Residual Axial Load Capacities was proposed, and its validity was examined. 3. It was experimentally revealed that columns for which axial load was decreased below the initial level showed larger collapse drift than columns for which axial load was kept constant.
