摘　　要：为了研究钢桁架连梁与剪力墙的空间作用,建立了6层带钢桁架连梁的三维剪力墙有限元模型,研究了不同尺寸的钢桁架连梁对剪力墙结构的力学性能的影响.分析结果表明,随着连梁尺寸增大,剪力墙的承载力随之增大,但变形性能和耗能性能明显降低;因此,需选择合适的连梁尺寸,才能保证剪力墙结构的抗震性能.Finite element models of 6-storey shear wall with steel truss coupling beam have been built to study the influences of steel truss coupling beam on spatial mechanical properties of shear wall structure. The results show that with the dimension increase of the truss, bearing capacity of the shear walls goes up, but the ductility and energy dissipation property obviously decline. So, suitable steel truss coupling beam is necessary in order to ensure seismic behavior of the shear wall structure.
