湘江财富金融中心T1塔楼结构高度324m,T2塔楼结构高度255m,两座塔楼均为超限高层,建筑要求由结构外框柱形成巨型斜交网格,结合幕墙变化达到建筑设计立面效果。结构设计结合建筑特点采用了较复杂的多重抗侧力结构体系,通过多种计算程序对结构整体进行了弹性和弹塑性计算分析、结构抗震性能化设计、外框柱稳定分析、关键节点有限元分析等,主体结构能达到设定的性能目标要求,结构体系具有有效的耗能机制和良好的抗震性能。 The T1 tower of Xiangjiang Fortune Financial Center has a height of 324m and a height of T2 tower of 255m. Both towers are overrun by high-rise buildings. The building requires a massive diagonal grid formed by structural columns and columns, which can be combined with curtain wall changes to achieve the building facade effect. Structural design combined with architectural features using a more complex structure of multiple anti-lateral force through a variety of computational procedures for the overall structure of the elastic and elastoplastic calculation and analysis of structural seismic performance design, stability analysis of the outer frame, the key node finite element Analysis, etc., the main structure can achieve the set performance targets, the structural system has an effective energy dissipation mechanism and good seismic performance.
