混凝土屋面板因特殊的生成环境及使用环境而产生显著初变形,采用ANSYS有限元分析软件,对顶层墙体受混凝土屋面板初应变引起的内力特性进行了非线性分析,初步定量揭示了墙屋面板应变引起体开裂机理,并在总结归纳典型分析结果的基础上结合工程应用提出建议。希望所做的工作对这类构件的设计及施工提供有价值的参考。
As the particular work environment and formation environment of the concrete roof-plate,the noticeable initial strain take place.By the finite element analysis software ANSYS,nonlinear analysis are made for internal force of the top wall based on the initial strain of concrete roof-plate,and crack mechanism based on the initial strain of the top wall and concrete roof-plate is initially revealed with rations.Summing up the achieved typical results and intergrating with the engineering application,the finished work are expected to provide a valuable reference for the designing and construction of this kind of structure.
