摘　　要：为提高装配式结构预制程度、解决剪力墙结构连梁剪压比不足问题,保证结构抗震性能,提出一种内置压型钢板装配式宽连梁。首先通过拟静力试验研究了内置压型钢板装配式宽连梁剪力墙抗震性能,然后通过结构数值模拟研究了采用该型连梁的12层剪力墙结构在地震波作用下的动力响应。研究结果表明:内置压型钢板装配式宽连梁剪力墙试件在水平往复荷载作用下,发生弯剪破坏,延性较好、耗能能力较强,与现浇连梁的剪力墙结构相比,采用压型钢板装配式宽连梁剪力墙结构抗震性能明显改善。In order to improve the prefabrication degree of the fabricated structure,solve the problem of insufficient shearcompression ratio of the shear wall structure and ensure the seismic performance of the structure,a profiled steel sheet built-in fabricated wide coupling beam is proposed.Firstly,the seismic performance of profiled steel sheet built-in fabricated wide coupling beam structure was studied by pseudo-static test,and then the dynamic response of the 12-story shear wall structure using this type of coupling beam under the action of seismic waves was simulated through structural numerical simulation.The results show that the profiled steel sheet built-in fabricated wide coupling beam shear wall specimen undergoes bending-shear failure and has good ductility and strong energy dissipation capacity under the action of horizontal round-trip load,compared with the shear wall structure of cast-in-place coupling beams,the seismic performance of the profiled steel sheet built-in fabricated wide coupling beam structure is significantly improved.
