叠合柱在某超高层办公楼的应用探析

Analysis on The Application Of The Overlap Column In A Super High-rise Office Building

钢管混凝土叠合柱由于具有承载力高、延性好、防火性好和施工较方便等优点,被广泛应用于在高层建筑结构中。为此,分析钢管混凝土叠合柱在某主体高度约200 m超高层办公楼中的应用情况,并采用YJK和Midas Building对该钢管混凝土叠合柱的结构体系进行整体验算,同时采用有限元分析软件,对叠合柱的节点进行补充分析。结果表明,结构体系合理、刚度和质量分布均匀,钢管混凝土叠合柱能较好地应用于超高层建筑中。

The steel pipe concrete overlapping column is widely used in high-rise building structures due to the advantages of high load capacity,good delay,good fire resistance,and convenient construction.This article introduces the application of the high-rise office building of the steel pipe concrete overlapping column in a high-rise office building of about 200 meters in a subject.Analysis software supplements the overlap column node.Results showed that the current structural design system is reasonable,the structural stiffness and quality are evenly distributed,and the concrete stack column of the steel pipe can be better applied to super high-rise buildings.
