摘　　要：考虑高强混凝土的收缩、徐变对竖向变形及结构应力的影响,运用有限元软件,结合武汉中心工程实例,对巨柱框架-核心筒-伸臂桁架结构体系施工过程进行力学模拟和受力性态分析。计算结果表明:在重力与施工荷载作用下,楼层的标高位置与设计位置存在变形差异,最大变形差异发生在塔楼中间部分;核心筒超前施工对塔楼的竖向变形存在一定的影响,但对整体变形影响较小,可以在施工过程中通过找平进行调整。Considering the influences of high strength concrete＇s shrinkage and creep deformation on the vertical deformation and the structural stress, using the finite element software, combined with Wuhan Centre Project,mechanical simulation and stress state analysis for giant column frame-core tube-canlilever truss structure system construction process were given. The calculation results show that in the gravity and construction load, the deformation exists between the elevation position of floor and the design position, maximum deformation difference occurred in middle of tower, the advance construction of the core tube has certain influence on the vertical deformation, but a small influence on the whole deformation, which can be adjusted by making level in the construction process.
