[關(guān)鍵詞] 組合砌體剪力墻 抗彎承載力 匹配關(guān)系 界限受壓區(qū)高度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.
