摘　　要：文中以某超高层建筑为例,对超高层钢结构中桁架层下连次柱施工进行研究。结果表明,设置支撑系统情况下桁架的最大挠度比未设置支撑系统的条件下降低了82.2%,设置支撑系统情况下桁架的最大应力比未设置临时支撑系统的条件下降低了69.6%。通过校准调整,各个构件的变形均满足设计方案的要求,施工质量良好,可为类似工程提供参考。Take a super high-rise building as an example to analyze the construction of super high-rise steel structure in this paper.The prac-tice shows that the maximum deflection of the truss with the support system is reduced by 82.2%compared with that without the support sys-tem.The maximum stress of the truss with the support system is 69.6%lower than that without the temporary support system.Finally,after calibration and adjustment,the deformation of each component meets the requirements in the design scheme,and the construction quality is good,which provides reference for similar solid projects.
