摘要
主要研究了现浇混凝土肋梁屋盖常发生的开裂问题,针对屋盖结构特定的工作环境,应用结构有限元分析软件ANSYS对混凝土屋盖在变温作用下的效应进行了较系统的数值分析,初步揭示了屋面板裂缝开裂机理及裂缝分布特征。
The crack problem of cast-in-place concrete rib-beam roof-plate is discussed in this paper. For the particular work environment of the roof-plate structure, the finite element analysis program ANSYS is adopted to study on it. By the numerical simulation, effect of the concrete roof-plate based on temperature difference is analyzed systemically. And this paper indicates the mechanisms and distributed characteristic of the concrete roof-plate cracks.
