摘要 基于分层壳单元,根据面积和刚度相等原则,计算得到2条对称于中性轴的连续"灌芯层"厚度和距截面中性轴的距离,并以此建立基于"灌芯层"分层壳单元的有限元分析模型.通过与试验结果进行对比,表明"灌芯层"分层壳单元具有很好的实用性,能较准确地模拟配筋砌块砌体剪力墙的非线性力学性能,可用于实际工程. The composite materials structure can be accurately simulated by multilayer shell element for it can be divided to multilayers according to the composition of different materials. Two continuous grouted layers are symmetrically set at natural axis based on multilayer shell element. Based on equality of area and stiffness, the thickness and distance from natural axis can be calculated, and the distribution of component materials can be determined. The numerical simulation results match well with those from the tests, so as to indicate that the multilayer shell element considering grouted layer has higher computational efficiency and can accurately simulate the nonlinear mechanical properties of reinforced block masonry shear wall.
