以某塔楼偏置的大底盘双塔楼框架-核心筒超高层结构为分析对象,根据工程特点,制定了罕遇地震下整体位移控制和不同重要程度结构构件的抗震性能目标。采用ABAQUS软件进行了罕遇地震下弹塑性时程分析,得出了整体位移指标和各结构构件性能水准控制结果,同时通过大震震害揭示出了结构薄弱部位,并针对性地优化了结构布置。
Taking the large-chassis double-tower frame-core-tube super-high-rise structure with an offset of the tower as the analysis object, according to the characteristics of the project, the overall displacement control and the seismic performance targets of structural components with different degrees of importance under rare earthquakes were formulated. The ABAQUS software was used to analyze the elasto-plastic time history under rare earthquakes, and the overall displacement index and the performance level control results of various structural members were obtained. At the same time, the structural weakness was revealed through the large-shock earthquake damage, and the structure was optimized in a targeted manner. Arrangement.
