摘　　要：系统地研究了配筋混凝土砌块砌体剪力墙的截面延性系数分析、截面屈服弯矩和极限弯矩计算、截面屈服曲率估算以及截面弯矩-曲率关系曲线建立的数值分析法,讨论了剪力墙轴压比、翼缘宽度、材料强度、配筋率和配箍特征值等因素对剪力墙截面延性的影响,提出了截面屈服曲率的估算公式。最后结合配筋砌块砌体剪力墙低周反复荷载试验,验证了配筋混凝土砌块砌体剪力墙截面延性数值分析法的可靠性。The numerical analysis method for reinforced concrete block masonry shear walls had been studied systematically,which is used to analyze the section ductility coefficient,to calculate the section yielding and ultimate moment,to estimate the section yield curvature,to analyze the moment-curvature relationship curves.The effect of axial compression ratio,flange width of shear wall,strength of materials,reinforcement ratio and reinforcement characteristic value on shear wall section ductility was discussed,and the estimating formulas of yield curvature of section were presented.The low-cyclic reversed loading test results of reinforced concrete brick masonry shear walls indicate that the numerical analysis method is reliable and effective.
