［摘要］基于ANSYS軟件提出一種超高層框架-核心筒結(jié)構(gòu)施工模擬方法。首先采用等效降溫法計(jì)算混凝土收縮效應(yīng)，采用ANSYS蠕變計(jì)算功能計(jì)算混凝土徐變效應(yīng)，然后利用生死單元功能來實(shí)現(xiàn)施工過程模擬，最后通過ANSYS APDL編寫程序進(jìn)行二次開發(fā)。并通過對實(shí)際工程的施工模擬，分析了施工過程與混凝土收縮徐變對核心筒和鋼框架柱的豎向變形、軸力、反力等的影響，為設(shè)計(jì)與施工的安全性提供參考依據(jù)。

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
