摘要 天津金塔大厦是我国第一座采用钢板剪力墙建造的高层建筑。主要抗侧力系统为钢板剪力墙和钢管混凝土柱组成的复合核心筒。为了研究该结构体系的抗震性能并提供设计指导，对两开间和五层钢板剪力墙的两个试件进行了低周反向荷载试验。第一个试件的无筋钢板通过高强螺栓与边界梁、柱框架连接。第二个试件的钢板通过焊接连接到边界框架，并且钢板通过槽钢加固。两个试件在加载过程中都表现出令人满意的能量耗散机制。对于具有螺栓连接的非刚性试件，相当大的屈曲后强度产生了优异的延展性和能量耗散性能，但螺栓连接和螺栓连接处的滑移...
AbstractTianjin Jinta Tower is the first high-rise building built with steel plate shear walls in China. The main lateral force resisting system is the composite core tube composed of steel plate shear walls and concrete-filled steel tubular columns. To investigate the seismic performance of this structural system and to provide design instructions, two specimens of 2-bay and 5-story steel plate shear walls were tested under low-cycle reverse loading. The unstiffened steel plates of the first specimen were connected to the boundary beam and column frame by high-strength bolts. The steel plates of the second specimen were connected to the boundary frame by welding, and the steel panels were stiffened by channels. Both specimens showed satisfactory energy dissipation mechanisms during the loading process. For the unstiffened specimen with bolted connections, the considerable postbuckling strength generated excellent ductility and energy dissipation performance, but a slip at the bolted connections and the b...
