摘　　要：抗风动力特性分析是海港大跨度钢引桥设计的一项重要内容之一,文中就跨度108m的海港钢引桥设计的工程实例,对钢引桥的特征值分析、横风下的静态屈曲分析、横风作用下的非线性屈曲分析几个方面的动力特性进行了阐述,分析结果表明拱桁式大跨度钢引桥抗风性能良好。Analysis of the dynamic characteristics of wind resistance is one of the important procedures for the design of a large span steel access bridge. Based on the design ofa 108-m span steel access bridge in a sea port, the analyses of the characteristic values of the steel access bridge and the analyses of the static buckling and non-linear buckling of the steel access bridge under the action of cross winds are expounded. The results of these analyses indicate that large span steel access bridges with arched brace girders produce good performance against winds.
