武汉世界贸易大厦结构设计
|
摘要
武汉世界贸易大厦地上 58层 ,地下 2层 ,采用C60高强混凝土。基于弹性地基假定 ,用有限元法分析了桩筏基础。利用内外筒支座条件和截面高度随内力变化的方法设计预应力折线板楼盖。在五十四层平面内收 ,选用人字形斜柱转换承托顶部 5层荷载。三道防线后浇带设计 ,保证后浇带防水质量并充分发挥应有的结构作用。主塔空间钢架设计和弹塑性地震反应分析保证建筑风格的实现 ,并满足抗震设防要求 ,使结构设计达到安全可靠、技术先进、经济合理的要求。
The author introduces the structural design of Wuhan World Trade Building.The building has 58 storeys over ground and 2 storeys under ground,and C60 high strength concrete is used.Elastic ground body assumption and finite element method have been adopted to analysis the piled raft foundation in design.Taking advantage of bearing factor and the changed section according to internal forces, prestressed folded concrete floor is designed.At 54th storey,the herringbone braced frame is used to transfer loads of 5 storeys upstairs.The design of three layer defence construction joint ensures the quality of waterproof.Space steel structure design and non liner dynamic seismic analysis method have brought about the new idea of architectural design and the require of antiseismic.Therefore,this design achieves safety,advanced technique and efficiency.
