摘　　要：通过某实际工程案例分析了单向(X向)少墙剪力墙结构在少墙方向结构的受力特性和刚度构成,研究Y向墙体在少墙方向的面外受力情况,并对面外受力的墙体区分不同部位,分别进行小震、中震、大震下的承载力验算,然后结合抗震性能目标给出相应结构设计措施。研究表明,小、中震下墙肢未屈服,但大震下部分墙肢屈服,因此,剪力墙面外受力的问题应予以充分地重视。Through an actual project study, the mechanical behavior and the stiffness composition of shear wall structure with few walls in one way （X direction） under lateral load were studied. The out-of-plane force conditions of shear walls in Y direction were studied. The different parts of the wall with out-of-plane forces were distinguished to carry out bearing capacity check under the frequent, fortification and rare earthquakes. And corresponding structure design measures were given according to the seismic performance goals. The above research shows that the walls do not yield under frequent and fortification earthquakes, but the part of the walls yield under the rare earthquake, so the problem of out-of-plane force on shear wall should be fully considered.
