摘要
以曹娥江大桥为工程背景,利用有限单元法对三种工况下的四肢桁式钢管混凝土拱肋截面在夏季各个时刻的温度场进行较为详细的分析,对截面有限元模型进行温度场函数拟合,并对拱肋在非线性温差作用下的结构行为进行探讨,得出的相关结论可用以指导该类结构的设计。
Taking Cao＇e River Bridge as engineering background, this paper uses finite element method to analyze the all time temperature field of concrete filled steel tube arch rib in the summer under three working conditions, fits the temperature function of cross-section finite element model, and studies the structural behavior of arch rib under the action of nonlinear temperature difference. Some useful conclusions are obtained in order to instruct this type of structure design.
