Abstract

Abstract: In oreder to study the influence of main cable angle of side span in suspension bridge, Xihoumen Suspension Bridge is taken as the protype,its finite element model is established by using bridge nonlinear analysis system BNLAS, which is developed by Southwest jiaotong University. This model is about a twin-tower single-span suspension bridge and its main cable span is 1650m, which has a single-span simply supported girder. Then, the influence of main cable angle on the force of suspension bridge is analyzed, through camparing the force changes of suspension bridge with different main ca- ble lengths of side spans

Key words: suspension bridgg;main cable angle of side span, BNLAS

摘要： 为了研究不同边跨主缆角度对悬索桥结构受力的影响,以西堠门大桥为原型,采用西南交通大学编制的桥梁非线性计算软件BNLAS,建立双塔单跨悬索桥计算模型,该模型中中跨主缆的跨度为1650m,加劲梁为单跨简支结构体系。通过比较不同边跨主缆跨度情况下悬索桥受力的变化,分析了主缆边跨角度的改变对悬索桥受力的影响。
