摘      要：The ductility of structures is vital to capacity design philosophy in seismic design. For a seismic shear capacity predictive equation for ductility reinforced concrete columns the shear test of 10 columns has been made. In the article, the shear contributions of concrete and transverse reinforcement as to the increasing of columns displacement ductility level are also investigated. The shear contribution of concrete is decreasing as the load and cycles of loading are increasing in the tests, while that of the transverse reinforcement is increasing till the transverse reinforcement is yielded. A seismic shear capacity design equation of columns with various ductility levels is given on the basis of test data collected from Japan and the tests. The equation is also proposed to modify Chinese Concrete Design Code (GBJ10-89).
