大跨径海港钢引桥抗风动力特性分析

Wind-reistance Dynamic Character Analysis for 108m-span Steel Access Bridge in Sea Port

海南实华炼化续建项目码头中的原油码头108m跨拱桁式钢引桥,其所处海域水深、风大、浪高,对于刚度较小的钢引桥,在此环境下的动力性能如何,是进行结构设计的一个重要内容。介绍了该大跨径钢引桥的抗风动力特性。

Some 108m - span truss arch steel access bridge are in one habour in Hai Nan province. It is the largest span in the same structure lied in pelagic sea. In addition, deep waters, heavy winds ＆hign waves are around the bridge. Thus, in structure design, wind- resistance dynamic character is very significant to steel actess bridge which is weak in rigidity. This paper detailedly introduce wind - resistance dynamic character tor such a large span access bridge.
