With reference to the deck unit erection crane used in construction of a newly built cable-stayed bridge without backstays with span arrangement(100+35) m in Suzhou City,the sudden skip load is used to simulate the dynamic action of the crane structure at the time the steel girder being hoisted.
以苏州市新建的一跨径组合为(100+35)m的无背索斜拉桥施工过程中的架梁吊机为背景,用突加阶跃荷载模拟钢梁起吊时的动力作用,采用有限元法建立架梁吊机结构的三维分析模型,对在空间受力形态下架梁吊机结构的动力反应问题进行了计算,探讨了钢梁起吊时起吊速度对架梁吊机结构动力反应及动力放大系数的影响,为架梁吊机结构的动力设计提供了理论依据。
