为了便于生态复合墙体的进一步推广,提出现砌加强肋生态复合墙体,并对该复合墙体抗剪承载力计算进行研究。首先对1/2比例现砌加强肋生态复合墙体进行低周反复荷载试验,分析了试件的抗剪试验结果;在试验研究的基础上,分析了影响现砌加强肋生态复合墙体斜截面抗剪能力的主要因素,结合已有抗震墙体相关资料,提出砌加强肋生态复合墙体抗剪承载力的通用计算公式,并给出了公式的适用条件。计算结果与试验结果的对比表明:理论推导所得的复合墙体斜截面受剪承载力计算公式,具有一定的精度,且概念非常明确,能够满足实际工程设计的需要。
In order to facilitate the further popularization of ecological composite wall, it is proposed to reinforce rib ecological composite wall, and to study the calculation of shear strength of the composite wall. At first, the low-cycle repeated load test was carried out on the half-cycle reinforced composite ecological wall with reinforced ribs, and the shear test results of the specimens were analyzed. Based on the experimental study, Based on the relevant data of the existing seismic walls, a general formula for calculating shear resistance of reinforced composite wall is put forward. The applicable conditions of the formulas are also given. The comparison between the calculated results and the experimental results shows that the calculation formula of the shear capacity of oblique wall of the composite wall derived theoretically has a certain accuracy and the concept is very clear, which can meet the needs of the actual engineering design.
