[摘要]在整个施工过程中结构是一个时变体系,结构的材料参数、几何参数、荷载边界条件都随施工进程而改变,结构竣工状态的内力和变形也是各施工步效应的累积结果,与施工过程和时间效应密切相关。施工过程分析是超高层建筑结构设计的重要内容。通过对非荷载效应在施工模拟中的应用研究,比较了不同收缩徐变模型的模拟差异、不同分析软件的应用特性,并通过对超高层建筑的施工模拟分析了收缩徐变对剪力墙和巨柱变形、结构竖向差异等因素的影响。

Abstract: Considering the time-vary structure under construction sequence, material parameters, geometrical parameters, loading and boundary condition change with the construction process, and the internal force and deformation of structure completion status are the cumulative results of the effect of each construction step, which are closely related with the construction process and the time effect. Construction sequence analysis is important for the structural design of highrise building. Construction analysis of a tall building, comparison of the different shrinkage and creep models and application characteristics of the different analysis softwares were studied, and the influence of shrinkage and creep on reinforced shear wall and vertical displacement difference were also discussed.
Keywords: non-load effect; construction process simulation; shrinkage and creep; high-rise building
