摘要
施工模拟是超高层建筑结构设计的重要内容。施工过程中结构的材料参数、几何参数、荷载和边界条件等都随施工进程而改变,施工结束后的内力和变形与施工过程、时间效应密切相关。利用Midas/gen有限元软件,对某超高层建筑结构进行了考虑混凝土收缩徐变影响的施工模拟研究,分析了收缩徐变对核心筒和框架柱竖向变形、竖向变形差及内力等因素的影响;并对不同施工方案下结构的竖向变形差异及风振影响等问题进行了研究。
Simulation is a super high-rise building construction structural design of important content. Construction process structure of the material parameters, geometrical parameters, load and boundary conditions are all changed with the construction process, after the construction of the internal forces and deformation and construction process, time effects are closely related. Using the Midas/gen structural finite element software, a high-rise building structures were considered effects of shrinkage and creep construction simulation studies to analyze the influence of the creep and shrinkage on the core barrel and frame column vertical deformation, vertical deformation and internal force poor factors. And the vertical deformation differences and other issues under different construction schemes were researched.
