摘要
以某超高层建筑为工程背景,选取CEB-FIP规范中混凝土材料的收缩徐变和强度模型,根据项目实际施工工序建立施工过程有限元模型。通过3种不同的施工过程模拟方案,得到了塔楼结构在各施工阶段的竖向变形情况,在对计算结果分析的基础上,得出了塔楼施工过程中竖向变形的发展规律。
Taking a super high-rise building as the engineering background,the shrinkage,creep and strength model of concrete materials in CEB-FIP specification are selected,and the finite element model of construction process is established according to the actual construction process of the project.Through three different construction process simulation schemes,the vertical deformation of the tower structure in each construction stage is obtained.Based on the analysis of the calculation results,the development law of the vertical deformation in the tower construction process is obtained.
