【摘要】 剪力墙构件是现代高层建筑结构中的主要抗侧向力构件.以两元件弹簧宏观墙单元模型为研究基础,以内置型钢桁架混凝土剪力墙、内置型钢框架混凝土剪力墙和普通钢筋混凝土剪力墙这3种中高剪力墙试件的单调及低周反复加载试验为模拟对象,确定了不同类型剪力墙中的弯曲弹簧单元的骨架曲线及滞回规则,提出了中高剪力墙模型中的弯曲弹簧恢复力模型.通过数值模拟得到了与试验结果吻合很好的滞回曲线,为此类剪力墙结构的弹塑性时程分析提供了一种有效单元模型.更多还原

【Abstract】 A shear wall element is the most important element resisting lateral loads.Based on the monotonic and cyclic loading tests of an SRC shear wall and ordinary reinforced shear wall,a two-spring macro wall element is used to simulate the mid-rise wall characteristics.The skeleton curve and restoring-force modal of the bend spring in the element is provided.The cyclic loading tests are performed on this element.The hysteretic curves agree well with the test results.The elasto-plastic time-history analysis for the shear wall structural calculation is effectively performed.更多还原
