摘要
本文将线性徐变理论和脆弹性破坏模型相结合,推导出计算混凝土浇筑块温度徐变应力的非线性有限元递推公式,并编制了计算机程序。最后以东江拱坝基础部分浇筑块为例进行了分析计算。
Combined linear creep theory with brittle-elastic failure model, the recurrence formulas of calculating the temperature creep stresses in pouring blocks of concrete under construction are derived in this paper. The computer program is designed and a numerical example, is presented. The numerical results indicate that the present nonlinear model is satisfied.
