[提要]  通过对两片长度不同的矩形截面钢筋混凝土抗震墙墙肢的计算分析，研究不同轴压比、不同层高的墙肢，为达到设定的层间弹塑性位移角，墙肢两端应设置的约束边缘构件的长度及其配箍特征值的大小；讨论了按《建筑抗震设计规范》( GB50011-2001)设置约束边缘构件的抗震墙墙肢的层间弹塑性位移能力。

By analyzing two rectangular shear walls with different section length, the required confined boundary element length and the required stirrup characteristic value of bound element are investigated for elastic-plastic story drift. The main parameters of the analyzed shear walls are elastic-plastic story drift, axial load ratio and story height. Elastic-plastic story drift capacity of shear walls with confined boundary elements according to "Code for Seismic Design of Buildings" ( GB50011-2001) is discussed.
Keywords: concrete structure; shear wall; confined bounclary elements; elastic-plastic; story drift
