摘要
对构造柱-芯柱组合配筋混凝土砌块墙体进行了低周反复试验,研究了以高宽比,开洞、设置水平钢筋等为影响参数对墙体的破坏特征,开裂荷载、抗剪承载力、极限水平位移等性能指标的影响。其中水平筋及高宽比对配筋砌体剪力墙中抗剪承载力和极限位移影响较大。提出了构造柱-芯柱组合配筋混凝土砌块墙体抗剪承载力的计算方法。
The tests of constructional columncore column composite of reinforced concrete block masonry wall under low cyclic is made, considering the actions of the different height-width ratio, open hole, the setting of the horizontal reinforcing steel bar to the destructive effects of the wall, and the influence of performance index including cracking load, shear capacity and ＂ultimate horizontal displacement. The horizontal bars and the height-width ratio influence the shear strength and ultimate displacement of reinforced masonry shear wall. The calculation method of shear strength of structural column-core column reinforced concrete block wall is presented.
