摘要
组合砌体剪力墙是由多种不同力学特性的材料复合而成的结构构件，其承弯能力的计算比较复杂。从各组成材料的本构关系出发，并借助平截面假定，给出了砌体材料和混凝土材料的匹配关系，推导了该类剪力墙在两种极限状态下的承弯能力，同时指出这两种极限状态的界限受压区高度。用本文公式计算的结果与弹塑性有限元及试验结果相比具有相当好的精度。
The composite masonry shear wall is structured by several materials of different mechanical characteristics and its bending bearing capacity is complicated to estimate. Based on the constitutional relationship of the materials and the assumption of cross section keep plane, the material match between concrete and masonry and the bending bearing capacity of two different kinds of limit state are given. Meanwhile, the critical compressive height of the two limit states are pointed out here. The comparisons between the results of proposed formulas and elastic-plastic FEM analysis and test results show that the proposed formulas have acceptable accuracy.
