[關(guān)鍵詞] 鋼筋混凝土 抗震墻 層間彈塑性位移角 邊緣構(gòu)件 約束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
