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.Keywords: reinforced concrete block masonry; shear wall; section ductility; numerical analysis*湖南省教育廳科研項目（12C0713）作者簡介：李明, 碩士, 講師, Email:hnistli@163.com參考文獻［1］李明, 汪夢甫. 配筋混凝土砌塊砌體剪力墻位移延性的數(shù)值分析［J］. 四川建筑科學(xué)研究, 2009, 35(4):68-70.［2］PRIESTLEY M J N，KOWALSKY M J.
