| Research Abstract |
Structural performance of short columns for newly designed reinforced concrete buildings was studied. The major findings from the study are as follows: (1) collapse drift of shear-failing RC column tends to be large as the main reinforcement ratio increases. This finding may indicate that column with shear failure mode could be used for structural design; and (2) columns for which axial load was decreased below the initial level showed larger collapse drift than columns for which axial load was kept constant, and as the greater the rate of axial load decrease, the larger the collapse drift.
