摘　　要：在混凝土剪力墙结构分析中,剪力墙截面刚度是一个必须计算的重要参数。根据悬臂剪力墙试件拟静力试验资料,建立了其侧移分析的简化力学模型;依据15个高强混凝土悬臂剪力墙试件的荷载-侧移试验结果,给出了这种剪力墙开裂、屈服和极限点的截面刚度退化系数。与试验结果的比较表明,本文提出的截面刚度退化系数,与试验结果总体上比较符合。Calculating the cross-section stiffness of shear wall accurately is integrated in concrete shear structure analysis.The simplified calculated model was established based on series pseudo-static experiments of cantilever shear wall.According to the load-lateral displacement results of 15 high strength cantilever concrete shear walls specimens,the coefficients of cross-section stiffness degradation of this concrete shear wall about its stages of crack,yield and ultimate posints were computed.Comparing these coefficients to experimental results,a roughly coincidence is found.
