摘要 为了解决薄钢板剪力墙结构中框架柱易发生破坏而失效的问题,将强度高、刚度大的PEC柱引入薄钢板剪力墙结构,作为竖向边缘构件形成PEC-SPSW结构,分别对1榀带H形钢柱、2榀带PEC柱的钢板剪力墙结构,进行了低周往复荷载作用下的抗震性能试验研究。通过分析该结构的承载力、初始刚度、耗能能力、应力分布及破坏模式,得到了带PEC柱的钢板剪力墙结构具有更好的抗侧刚度、承载力和耗能性能。PEC柱构件对薄钢板有更好的锚固约束作用,从而使得薄钢板充分发挥屈曲后强度作用,带PEC柱的钢板剪力墙结构有更好的发展前景。

Abstract:To study the failure problems of frame columns in the thin steel plate shear wall structure, the PEC column with high strength and stiffness is proposed, which can be used for a vertical edge member forms PEC-SPSW structure. Experimental study on seismic behavior of A frame with H-shaped steel columns and two frames with PEC Columns under cyclic loading, and the bearing capacity, initial stiffness, energy dissipation capacity, stress distribution and failure pattern were analyzed.The test results indicate that the steel plate shear wall structure with PEC columns has better lateral stiffness, bearing capacity and energy dissipation. The PEC column has better anchorage and restraint effect on the thin steel plate, thus making the thin steel plate fully exerting the post-buckling strength, and the steel plate shear wall with PEC column has good prospects for application.
