Abstract:

利用25片足尺全灌芯配筋砌块砌体剪力墙的低周往复荷载试验,研究了此种墙体在发生剪切型破坏模式下的恢复力模型。选取截面宽度包含190mm、240mm和290mm三种块型的墙体试验,研究了不同砌块孔洞率、竖向压应力、竖向和水平配筋率、墙体高宽比等参数对墙体破坏模式的影响。利用试验记录提出骨架曲线,其归一化骨架曲线符合带下降段的三折线模型。对试验数据进行回归分析,得到满足指数衰减规律的刚度衰减方程。提出适用于发生剪切型破坏模式的配筋砌块砌体剪力墙的滞回规则,此规则在卸载阶段用两折线表示,两折线采用不同的刚度值,第一卸载段采用初始刚度,第二卸载段采用本文提出的刚度衰减方程。该文提出的滞回模型能够较好模拟配筋砌块砌体剪力墙捏拢现象,模拟出的滞回曲线与试验记录到的曲线吻合良好。
