斜拉桥运营阶段温度效应分析

The temperature effect analysis of cable stayed bridge operation stage

以苏通大桥为计算模型,将斜拉桥的温度荷载分解为体系温差、索梁(塔)温差、主梁温度梯度以及主塔的温度梯度来考虑,利用大型通用有限元软件ANSYS研究了斜拉桥运营阶段的温度静力响应,得出了斜拉桥的温度效应不容忽视的结论。

With Sutong Bridge as calculation model, the temperature loading of cable stayed bridge was decomposed into system temperature difference, cable beam temperature difference, main beam temperature gradient and main column temperature gradient, the temperature static response of cable stayed bridge operation stage was studied with large common finite element software ANSYS. It concluded that the temperature effect of cable stayed bridge was not ignored.
