摘要： 为了避免焊接造成的残余应力，通过螺栓连接的端板将上下2块钢板连接，形成一种延性和耗能能力更好的全螺栓连接钢板墙.通过有限元建立全螺栓连接和传统焊接连接钢板墙模型，对比两种钢板墙在单向推覆和往复荷载作用下的荷载位移曲线、抗侧承载性能、能量耗散系数、刚度退化和承载力退化等性能.结果表明，在单向推覆作用下全螺栓连接钢板墙的抗侧承载力与传统焊接形式较为接近，但初始刚度比传统形式下降了11%;在往复荷载作用下，全螺栓连接形式表现出更好的整体耗能能力，刚度退化更平缓.该类钢板墙还便于生产和安装，在今后的工程应用中值得广泛的推广和应用.

Abstract: In order to avoid the residual stress caused by welding， the upper and lower steel plates are connected by the end-plate with bolts to form a fully bolted steel plate shear wall (SPSW) with better ductility and energy dissipation capacity. The models of fully bolted SPSW and welded SPSW were established and analyzed by the finite element method. The load-displacement curve， lateral bearing capacity， energy dissipation capacity， stiffness degradation， and bearing capacity degradation of the two kinds of steel plate shear walls under unidirectional push-over and reciprocating load were compared. The results show that， under the action of unidirectional push-over， the lateral bearing capacity of the SPSW with full bolted is close to that of the traditional form， but the initial stiffness is 11% lower than that of the traditional form. Under the reciprocating load， the SPSW with full bolted shows a better overall energy dissipation capacity， and the stiffness degrades slower. This form of SPSW is also convenient for production and installation， and worth to extensive promotion and application in the future engineering application.
