【提要】  短肢剪力墙中长厚比小于等于5的墙肢设计是高层住宅设计中经常遇到的问题。从墙体受力特征、SATWE软件的计算结果的角度，阐述了软件中墙肢受压区端部钢筋合力点到受压区边缘的距离aa的取值应该因墙肢长厚比的不同而不同，以及用软件中的相关工具箱进行补
充计算的可行性，分析了计算程序中墙体竖向分布钢筋配筋率对墙端范围内钢筋面积的影响。最后给出了参数aa的建议取值。

Design of Short Branch Shearwall with Different Ratios of Length to Thickness  in Shearwall Structur/Liu Huizhen,Chen Jiehou,Zhang Yuhong(Ho & Partners Architects & Engineers (China) Ltd.,Shenzhen 518001,China)
Abstract:In the highrise shearwall structure,the short branch wall,that the ratio of length to thickness is less than 5,is widely used.Based on the bearing characters and calculation results of SATWE software,the viewpoint that the factor aa should be verified with the different ratios of length to thickness of walls,and the feasibility of complement calculation using relative toolbox in the software is analyzed.The effect of reinforcement ratio of vertical distribution bars on the amount of bar in the end of the wall branch is discussed.The value of factor aa is suggested.
