超高层建筑筒中筒结构体系之探讨

Discussion on the Tube-in-tube Structural System of Super High-rise Building

高层建筑是反映城市经济繁荣和社会进步的重要标志。随着社会与经济的蓬勃发展,要求建筑物所能达到的高度与规模不断增加。高层建筑的突飞猛进,从技术层面来看,得益于力学分析方法和计算技术的发展以及结构设计的进步。通过收集已建成的筒中筒结构体系的工程实例资料分析,建立了模拟500 m、600 m和700 m高度的计算模型,通过试算,总结了结构设计的主要控制指标的影响。模拟模型的竖向构件布置及尺度,也为相似工程的方案设计提供参考。

High-rise building is an important symbol reflecting the city＇ s economic prosperity and social progress.With the rapid development of society and economy,the increasing height and size of the buildings would be required.The development of mechanical analysis method,computing technology and progress in mechanical structure design promote to make a spurt of progress of high-rise buildings.Numerical models for 500 m,600 m and 700 m height were simulated to investigate the main control indexes of structural design based on collecting engineering examples of tube-in-tube structure.The parameters of vertical members from the numerical models can be used for reference in similar projects.
