摘要
针对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的特征,采用ANSYS有限元分析软件,分析混凝土屋面板初应变产生的内力特性及开裂机理,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 ,internal force and crack mechanism of the concrete roof-plate based on the initial strain are analysed. Sum up the achieved typical results and intergrate with the engineering application, The finished work are expected to provide a valuable reference for the designing and construction of the concrete roof-plate.
