湛江万达广场超高层连体结构抗震性能设计

Performance-based seismic design of super high rise connected structure in Zhanjiang Wanda Plaza

以湛江万达广场超高层连体结构为例,采用框架核心筒结构体系,在中高区用钢结构桁架将两塔楼进行刚接,采用基于性能的抗震设计方法进行分析设计,结合拟定的抗震性能目标,采用YJK,Midas Gen,对结构整体进行了分析,并利用Abaqus进行动力弹塑性分析,计算结果表明结构抗震性能满足规范要求。

Taking the super high rise connected structure of Zhanjiang Wanda Plaze as an example. The structural style is frame core tube which is connected by steel truss. The performance-based seismic design method is adopted to analyze and design the project. Combining with the pro-posed seismic performance objectives. The whole structure is analyzed by YJK and Midas Gen. The dynamic elastic-plastic analysis is carried out by Abaqus. The results show that the seismic performance of the structure meets the requirements of the code.
