摘要
重庆新华国际大厦局部托柱转换体系承担了上部54层的荷载,为追求经济、合理的设计方案,对钢筋混凝土深梁、型钢混凝土组合梁、空腹桁架、叠层空腹桁架、斜腹桁架、叠层斜腹桁架6种方案进行了试算和比选,最终拟采用型钢混凝土空腹桁架方案。介绍了空腹桁架方案的受力分析、构造措施等,并对分析模型、计算参数、杆件设计等问题进行了探讨。
Xinhua International Building located in Chongqing requires a frame column underpin transfer system which supports large load from 54 floors.In order to discover an economical and rational way to design the project,6 schemes including deep beam,steel reinforced concrete composite beam,vierendeel truss,two-storey vierendeel,diagonal truss and two-storey diagonal truss were discussed.Vierendeel truss with steel reinforced concrete composite members was adopted.Mechanical behaviors and construction measures of the vierendeel truss were introduced,and the analysis model,parameters,member design methods and etc.were also investigated.
