建筑模网混凝土剪力墙抗剪承载力分析

Shear resistance capacity analysis of mould meshwork concrete shear wall

建筑模网混凝土剪力墙是一种新型的组合结构。为了分析模网混凝土剪力墙的抗剪承载力,整理了21组模网混凝土剪力墙的抗震拟静力试验数据,采用灰关联分析方法分析了各影响因子对其抗剪强度的影响程度;并对抗剪强度进行了回归分析。分析结果表明,在模网混凝土抗剪强度的各影响因子中,轴力的影响权重最大,墙体有效面积的影响次之,折钩拉筋的影响最小。回归分析亦得到了相同的结论。

Mould meshwork concrete shear wall is one of new type of composite structural system. In order to study the shear resistant capacity of mould meshwork concrete shear wall, 21 quasi-static test results were collected and influence factors which affect the shear resistant capacity of mould meshwork concrete shear wall were analyzed through grey-correlation analysis method. The expressions to estimate the shear resistant capacity of mould meshwork concrete shear wall were proposed based on regression analysis. It is found that, among the influence factors, axial compressive force is the most important, the second one is the effective area of the wall, the effect of stiffening ribs in the latitudinal direction shows small influence. And regression analyses show the same conclusion.
