Practical Method of Computing Lateral Wind Effect for Long-span Suspension Bridges
Author(s): 
Pages: 1-4
Year: Issue:  2
Journal: BRIDGE CONSTRUCTION

Keyword:  悬索桥长跨桥风载荷结构分析计算方法;
Abstract: 首先提出一种新的求解大跨径悬索桥侧向风载效应的实用方法--修正的膜理论(这种方法综合考虑了风的三分力系数和主缆索力随风速变化的非线性效应),然后导出了有关计算公式,给出了计算流程图.最后,以虎门大桥为例进行了数值计算,并与其它方法进行了比较.
