摘要
铝合金作为一种优质的新型桥梁结构材料,具有轻质高强、易养护、低碳环保、施工便捷、景观性强等特点.近年来,铝合金结构在城市人行天桥中已被较多应用,但少有大跨径铝合金人行天桥应用实例.以佛山市禅城区佛山大道(澜石路口)人行天桥为例,详细介绍大跨径铝合金人行天桥上部结构设计.通过MIDAS及3D3S有限元模型,对大跨径铝合金人行天桥上部结构进行选型分析,可为大跨径铝合金人行天桥上部结构设计提供参考.
Abstract
As a high-class new bridge structural material,the aluminium alloy has the characteristics of light and high strength,each maintenance,low-carbon environmental protection,convenient and fast construction and high landscape performance.In recent years,the aluminium alloy structure has been more applied in the urban footbridges.But there is rare application case of long-span aluminium alloy footbridge.Taking Foshan Avenue Footbridge(intersection of Lanshi Road)in Chancheng District of Foshan as an example,the superstructure design of the long-span aluminium alloy footbridge is introduced in detail.The superstructure of the long-span aluminium alloy footbridge is selected and analyzed through MIDAS and 3D3S finite element models,which can be referred for the superstructure design of the long-span aluminium alloy footbridge.
