顺德绿地商业中心项目5#楼总高度229.6m,采用了框架-核心筒结构体系。分析了结构的超限情况并确定了抗震性能目标,采用了基于性能的抗震设计方法,对结构进行了小震弹性、中震等效弹性计算及大震下的弹塑性时程分析及转换桁架节点的有限元分析。以上分析可保证结构实现预先设定的抗震性能目标。
Shunde Green Business Center Project # 5 building total height of 229.6m, using a framework - the core tube structure system. Based on the analysis of the structural overrun situation and the determination of the seismic performance objectives, the performance-based seismic design method is adopted. The structure is simulated with small earthquake elasticity, moderate earthquake elastic elasticity calculation, elastic-plastic time history analysis under large earthquake and transfer truss Finite element analysis of nodes. The above analysis can ensure that the structure to achieve the pre-set seismic performance goals.
