Abstract:
To study the seismic performance of double-skin steel-concrete composite box(DSCB)piers, a total of 11 DSCB pier specimens were tested under bidirectional cyclic loading. The effects of the loading pattern, the steel plate thickness, the axial load ratio, the slenderness ratio and the aspect ratio were taken into consideration. The damage evolution process and failure modes of the tested specimens are presented in detail. Test results are also discussed in terms of the hysteretic curve, skeleton curve, ductility and energy dissipation capacity of DSCB pier specimens. It can be concluded that the hysteretic performance of DSCB piers in one direction is affected and weakened by the cyclic loading in the other direction. DSCB piers under bidirectional cyclic loading exhibit good performance in terms of load carrying capacity, ductility, and energy dissipation capacity. Overall, DSCB piers can meet the basic aseismic requirements. The research results can be taken as a reference for using DSCB piers as high piers in bridges in strong earthquake-prone areas.
为研究双壁钢箱混凝土组合墩柱(DSCB墩柱)的抗震性能, 对11个DSCB墩柱试件进行了双向拟静力试验, 考虑了加载模式、钢板厚度、轴压比、长细比、截面长宽比等主要因素对DSCB墩柱抗震性能的影响.给出了试件的主要损伤演化过程和破坏模式, 并从滞回曲线、骨架曲线、延性和耗能能力等方面对试验结果进行了分析.结果表明:水平双向加载下, DSCB墩柱一个方向的损伤劣化会加剧另一个方向的损伤;DSCB墩柱在水平双向荷载作用下, 具有良好的强度、延性和耗能能力, 能够满足强震区高墩桥梁的抗震要求.该研究可为DSCB墩柱在强震地区高墩桥梁中的应用提供依据.
