根据悬索桥的基础理论及其加劲梁基本结构形式的发展演变和设计流派的研究,结合美国塔科玛桥板式加劲梁悬索桥的风毁工程实例,着重对板式加劲梁结构的抗风稳定性和工程措施再度研究分析。在此基础上,结合实桥设计将研究成果分别应用于预应力板式加劲梁悬索桥和钢板式加劲梁悬索 According to the basic theory of suspension bridge and the development and evolution of the basic structure of its stiffening girder and the school of design, this paper, combined with the example of the wind damage project of the Takaerma bridge plate stiffened girder suspension bridge, focuses on the wind-induced stability and engineering Measure again study and analysis. On this basis, combined with the actual bridge design, the research results are respectively applied to prestressed plate girder suspension bridge and steel girder suspension cable
