摘要
综合考虑静风荷载非线性和结构几何非线性因素的影响,计及风速沿桥梁结构高度的变化,建立了单索面斜拉桥静风非线性的分析模型。结合淇澳大桥进行分析计算,探讨了风速沿塔柱高度分布不均匀性、静风荷载非线性等因素对单索面斜拉桥空气静力行为的影响。
The analysis model for static wind nonlinearity of single cable plane cable-stayed bridge is established, taking comprehensive account of influences of the static wind load nonlinearity, geometric nonlinearity and also wind speed changes along the bridge structure height. With reference to Qi'ao Bridge, the analytical calculations are conducted, and the influences of non-uniformity distribution of the wind speed along the height of the bridge pylon shafts, the static wind load nonlinearity, etc. on the aerostatic performance of the single cable plane cable-stayed bridge are discussed.
