中文摘要:

合成的钢板的地震表演砍由一个钢盘子组成的墙(CSPSW ) 砍有面板借助于螺栓或接头纳入了一个或双方的增强的水泥(RC ) 的墙(SPSW ) 试验性地被学习。shear 墙被连接到框架横梁然而并非到柱。这安排制止薄墙的钢板弄弯的可能的 out-of-plane,显著地因此增加全面的墙的适用的能力和韧性,并且阻止早熟的外套或框架列的本地弄弯失败。从一个实际观点,这些答案能在是的一块地板提供空地这类合成砍有相对小的方面比率的墙能被放沿着一个海湾的平行。在这研究,四 CSPSW 和一 SPSW 被测试,结果证明 CSPSW 和 SPSW 拥有了好韧性。为 SPSW 独自一个,弄弯出现了并且导致了忍受能力和精力驱散能力的减少。另外,在角落焊接 stiffeners 被显示是增加 CSPSW 的精力驱散能力的一个有效方法。

英文摘要:

The seismic performance of composite steel plate shear walls (CSPSWs) that consist of a steel plate shear wall (SPSW) with reinforced concrete (RC) panels attached to one or both sides by means of bolts or connectors is experimentally studied. The shear wall is connected to the frame beams but not to the columns. This arrangement restrains the possible out-of-plane buckling of the thin-walled steel plate, thus significantly increasing the bearing capacity and ductility of the overall wall, and prevents the premature overall or local buckling failure of the frame columns. From a practical viewpoint, these solutions can provide open space in a floor as this type of composite shear walls with a relatively small aspect ratio can be placed parallel along a bay. In this study, four CSPSWs and one SPSW were tested and the results showed that both CSPSWs and SPSW possessed good ductility. For SPSW alone, the buckling appeared and resulted in a decrease of bearing capacity and energy dissipation capacity. In addition, welding stiffeners at corners were shown to be an effective way to increase the energy dissipation capacity of CSPSWs.
