| 摘 要： | 采用谐波叠加法模拟了巫峡长江大桥处的随机风场，应用有限元分析软件ANSYS建立了该桥的有限元模型，在此基础上，对该桥进行了非线性时域抖振分析。并计算了该桥的静风、阵风荷载响应。分析结果表明：考虑几何非线性会增大钢管混凝土拱桥的横桥向及扭转抖振响应，该桥的脉动风不可忽视。

| Abstract: | The wave superposition method was used to simulate the stochastic wind fields at the site of Wu Gorge Bridge over Yangtze River.The finite element model of the bridge was established with a FEM analysis software ANSYS,on which the nonlinear buffeting analysis for the bridge in time domain was carried out.In addition,the response of the bridge with static wind loads and with gust loads were calculated.The results show that the fluctuating wind of the bridge should not be neglected since the geometric nonline... |
