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).

摘要：1 巩义市陇海路石河道大桥概况巩义市陇海路石河道大桥,位于巩义市市区,是连接巩义市新城区与老城区的重要通道。大桥全长510.26m,桥面净宽:21m+2×2.5m(人行道)。采用10×50m简支 T 型梁,5孔一联。钻孔灌注桩基础。鉴于大桥位于两台地之间,两岸相对高差较大。桥面标高抬得较高,桥面距河底大约36m,致使位于西岸的0~#桥台填土高达18.56m。
