摘　　要：研究搭接柱转换结构在超高层中的应用,对搭接部位进行了有限元等细致分析。发现搭接柱转换的上下端楼面存在很大的反向轴力,尤其是受拉力情况下,需要通过专门的分析设计来满足承载力、正常使用和耐久性的要求;搭接区内有很大的压应力,也存在较大拉应力,需要合理布置钢筋或型钢,减少混凝土开裂或裂缝的发展;搭接区的相邻上下柱中同样存在应力集中,可采用适当构造措施和局部钢筋加强等方式来解决;说明搭接柱转换在一定条件下可以应用在超高层结构中。Study the application of lapped column transfer structure in super high-rise building,and the finite element analysis is carried out for transfer structure.According the analysis results,there is a large reverse axial force on the upper and lower floors of lapped column transfer structure,especially in the case of tension,special analysis are required to meet the requirements of bearing capacity,normal use and durability.There are large compressive and tensile stress in the lapped column.It is necessary to arrange reinforcement or steel to reduce concrete cracking.There is stress concentration in the adjacent upper and lower columns.It needs to be solved by proper Structural construc-tion measure and local reinforcement.Under some conditions,lapped column transfer structure can be used in super high-rise buildings.
