摘要
应用大型有限元软件对钢管混凝土拱肋成型过程中水化热影响下的结构温度场和温度内力进行计算,分析了不同混凝土浇筑温度下的拱肋温度场及其对拱肋成型时残余温度内力的影响.
The temperature field and inner force of concrete-filled steel tubular (CFST) rib subjected to cement hydration heat during its growth is calculated by using general finite element program. When the concrete is constructed in different temperature, the temperature fields and the inner force of the concrete-filled steel tubular rib are different.
