采用粘弹性连接改善高桩码头抗震性能分析

Analysis in Improving Earthquake Resistance Ability of High Pile Wharf by Viscoelasticity Connection

从以往高桩码头地震震害实例分析中不难发现,在地震动作用下,高桩码头破坏存在直桩节点破坏情况,致使码头板面整体支撑系统失效,码头台面倾覆宣告码头报废。试从改变直桩与横梁间的连接方式来提高高桩码头整体抗震能力,阐述粘弹性连接在高桩码头抗震方面的运用。

It is not to be difficult to discover that,from the formerly example of high pile wharf harms in earthquake by analysis ,the straight pile pitch point yielded is the primary destruction shape under the seismic motion function. And this will lead to entirety props up system become invalid ,then the wharf floor overturned announce the wharf destroyed. For the sake of improving the high pile wharf whole earthquake resistance ability, this paper changes connection way between the straight pile and the cross beam. For the more discussing the applyment of viscoelasticity connection in high pile wharf earthquake resistance.
