The minimum performance that is reauired for columns designed by the old code during severe earthquakes is to support axial load, or escape from axial collapse. However, in the past collapse tests of RC columns failing in shear after flexural yielding have not been done although those of columns failing in shear before flexural yielding have been done. Therefore, it is intended in this study to conduct such test. Test variables are amounts of transverse and longitudinal reinforcement and loading cycles. The effect of the variables on modes of shear failure and lateral drift-shear force relations up to the collapse are studied. An eauation to predict lateral drift at collapse is also presented, where the ratio of comouted shear and flexural strengths are used.
