【摘要】：深圳金港大厦工程是建造在7度抗震设防烈度区的大底盘、多塔楼、多重连体的多项"超限"工程。通过对连接体与塔楼的连接方式(强连接、弱连接)进行对比分析,并根据项目的特点,最终确定强连接为最佳连接方式。采用基于性能设计的抗震方法,对连体结构中重要构件,如连接体钢构件、节点及与连接体相连的竖向构件抗震性能目标定为设防烈度地震作用弹性、罕遇地震作用不屈服;底部加强区剪力墙抗震性能目标定为设防烈度地震作用受剪弹性、受弯不屈服;应用SATWE、MIDAS及ABAQUS等有限元分析软件,对结构在多遇地震、设防烈度地震和罕遇地震作用下进行计算分析。结果表明:整体模型各项指标满足规范要求,能够实现设定的抗震性能目标。
[Abstract]:Shenzhen Jingang Building is a large chassis, multi-tower and multi-connection "overrun" project which is built in the 7-degree seismic fortification area. By comparing and analyzing the connection mode (strong connection, weak connection) between the connecting body and the tower, and according to the characteristics of the project, it is finally determined that the strong connection is the best connection mode. Based on the performance design method, the seismic performance target of the important members of the connecting structure, such as the steel members, the joints and the vertical members connected to the connecting body, is set as the seismic elasticity of the earthquake protection intensity, and the earthquake action is not yielding when the earthquake action is rare. The seismic performance target of the shear wall in the bottom strengthening area is set as the shear elasticity and bending non-yield under the earthquake action of the fortification intensity. Using finite element analysis software such as SATWE,MIDAS and ABAQUS, the structure is calculated and analyzed under the action of frequent earthquake, fortification intensity earthquake and rare earthquake. The results show that each index of the whole model meets the requirements of the code and can achieve the seismic performance target set.
