[摘要]基于ANSYS软件提出一种超高层框架-核心筒结构施工模拟方法。首先采用等效降温法计算混凝土收缩效应,采用ANSYS蠕变计算功能计算混凝土徐变效应,然后利用生死单元功能来实现施工过程模拟,最后通过ANSYS APDL编写程序进行二次开发。并通过对实际工程的施工模拟,分析了施工过程与混凝土收缩徐变对核心筒和钢框架柱的竖向变形、轴力、反力等的影响,为设计与施工的安全性提供参考依据。

Abstract: A kind of method based on ANSYS was provided, which could simulate the construction process of high-rise frame-corewall structure. Firstly, the equivalent cooling method was used to calculate the shrinkage effect of concrete, and the creep calculation function supply by ANSYS was used to calculate the creep effect of concrete. Secondly, construction process simulation was realized by using birth and death element. Lastly, the language program APDL of ANSYS was used for secondary development to achieve construction simulation. Through construction simulation of a project, construction process and the shrinkage and creep were analyzed, which had an impact on vertical deformations, axial force and reaction of corewall and steel frame column. It provided the reference basis for the safety of the design and construction.
Keywords: frame-corewall structure; construction process simulation; shrinkage and creep; vertical deformation; change of axial force
