双钢板-混凝土剪力墙轴心受压性能试验研究

双钢板-混凝土剪力墙是由钢板和混凝土通过抗剪连接件连接组成的新型竖向组合构件和抗侧力构件，其作为一种新型结构具有结构强度高、抗震性能好、施工方便快捷等特点。但对于这种新型结构，设计应用多以具体工程具体研究的方式进行，缺少专用的规范标准。为研究双钢板-混凝土剪力墙的轴向受力性能，完成了4片双钢板-混凝土剪力墙的轴心受压试验，分析了剪力墙在轴心荷载作用下的受力性能和破坏形态，探讨了不同距厚比和对拉螺栓数量对钢板局部屈曲、破坏形态以及承载能力的影响规律。试验结果表明，距厚比对墙体的局部屈曲、破坏形态有较大的影响，但对刚度和承载力影响并不十分显著。

Experimental Research on Axial Compressive Behavior of Shear Wall with Double Steel Plates and Filled Concrete

The shear wall with double steel plates and concrete filled is a new type of vertical composite member and lateral resistant member. And it has the advantage of high strength, good aseismic behavior, easy construction etc. But in the design and application process, the specific method was studied for the specific project; there was no universal approach, code and specification for this new type structure. In order to study the axial mechanical behavior of the shear wall with double steel plates and concrete filled, axial compressive tests on four wall specimens were conducted. The mechanical behavior and failure modes were analysized under axial compressive loads, and influence of the distance to thickness ratio and the number of pull bolt on the local bucking of steel plates, failure modes and bearing capacity were investigated. The results indicated the distance to thickness ratio had significant effect on initial buckling of steel plate and failure modes of shear wall but had little effect on the stiffness and bearing capacity of walls.
