The mechanical characteristics of the setback super-tall structure are complex, and the design is difficult. In the actual analysis and design process, the relevant influencing factors should be fully considered. In this paper, the fine construction simulation analysis of the super-tall structure is carried out. Based on the shrinkage test of concrete members, the CEB-FIP 90 shrinkage model is modified in terms of the parameters of cross-section shape and size. The modified model is used to calculate the shrinkage strain of concrete, and the influence of uneven settlement of foundation and seasonal temperature on the structure is considered in the construction simulation analysis. The influence proportion of each non-load effect on the horizontal displacement, vertical displacement, and internal force of key components is obtained. The refined construction analysis results are compared with the field monitoring data, and the data are in good agreement.

后退超高层结构施工全过程非荷载效应影响研究

后退超高结构力学特性复杂，设计难度大。在实际分析和设计过程中，应充分考虑相关影响因素。本文对超高层结构进行精细施工模拟分析。基于混凝土构件的收缩试验，对CEB-FIP 90收缩模型的截面形状和尺寸参数进行了修正。采用修正模型计算混凝土收缩应变，施工模拟分析中考虑了地基不均匀沉降和季节气温对结构的影响。得出各非荷载作用对关键部件水平位移、竖向位移、内力的影响比例。将精细化施工分析结果与现场监测数据进行对比，数据吻合较好。
