摘　　要：为了提高结构抗震性能,常在结构底部、加强层等关键受力部位或者立面收进等薄弱部位设置钢板组合剪力墙。广州东塔工程在核心筒与伸臂桁架连接的部位,剪力墙内设置了钢板,采用ABAQUS软件对其进行动力弹塑性分析,研究在罕遇地震作用下的结构变形特征、伸臂桁架内力、剪力墙塑性损伤等非线性动力响应。结果表明,与普通钢筋混凝土剪力墙相比,在与伸臂桁架连接的核心筒部位采用钢板组合剪力墙,能够有效控制结构变形和减轻因刚度突变而造成的损伤,改善结构的抗震性能。In order to improve the seismic performance,steel plate concrete composite wall was used at the key parts such as the bottom of structure,the story with outriggers and belt members,and etc.Steel plate concrete composite wall was used in Chow Tai Fook（Guangzhou） Center at the joints of core wall and outrigger trusses.Dynamic elasto-plastic analysis by ABAQUS software was carried out to analyze the nolinear dynamic responses of the structure under rare earthquake,including the deformation,outrigger trusses force and shear wall damage,and etc.The results show that compared with the ordinary concrete wall,the steel plate concrete composite wall have good seismic performance,such as effectively controlling the structure deformation and reducing the damage caused by stiffness lose.
