| 以苏通大桥为背景，调研各国规范对斜拉桥温度作用的相关规定，进而研究超大跨径钢斜拉桥的温度静力响应。研究将斜拉桥的温度作用分为体系温差、索梁（塔）温差、主梁温度梯度、主塔温度梯度四个方面分别讨论，利用考虑几何非线性影响的有限元软件ANSYS计算分析斜拉桥的温度效应及各构件对温度的敏感性。分析结果可以为今后同类桥梁的设计或计算提供参考和依据。 |
| 英文摘要: |
| Based on the background of Sutong Bridge, this paper investigates several codes of the temperature acts on cable stayed bridges, and studies the static response to temperature acts of long span steel cable stayed bridges. The temperature loads consist of four parts as follows: uniform temperature component, temperature differences between cables and deck (or tower), temperature differences for bridge decks, and temperature differences for bridge towers. ANSYS, the finite element software considering the geometric non linear effect, is applied to analyze the temperature effects on cable stayed bridges and the sensitivity of each structural member. The results can be referenced for the design or calculation of similar bridges. |
