天津高银117大厦施工期工况模拟及计算分析

Simulation and Calculation Analysis of the Construction Period of Tianjin Gaoyin 117 Building

利用有限元软件ANSYS对天津高银117大厦工程进行了施工阶段核心筒非线性稳定分析,该分析考虑了几何非线性、材料弹塑性、初始几何缺陷等。并考虑了竖向荷载组合、水平风荷载的作用。通过上述分析,给出各种状态下结构可能的失稳模式与安全荷载系数。

In this paper,the finite element software ANSYS is used to analyze the nonlinear stability of the core tube in the construction stage of Tianjin Gaoyin 117 building. The geometric nonlinearity,material elastic plasticity and initial geometric imperfections are considered in the analysis. Meanwhile,the vertical composite loads and horizontal wind load are considered. By this analysis,the structural possible unstability load mode and safety load factor are put forward.
