提篮式系杆拱桥承载能力评定研究

The Study on the Loading Capacity Evaluation of Basket-tied Arch Bridge

提篮式系杆拱桥造型美观,在城市中采用较多,但其受力复杂,评定承载能力存在较大难度。在确定桥梁结构承载能力时,确定外荷载作用下力传递路径及内力分布较为关键。针对提篮系杆拱桥的研究现状,采用建模分析和实桥试验相结合的方法,解决试验数据和现场数据较少、机理研究不足等问题。

For the present research situation of basket-tied arch bridge, using the method of combination of modeling analysis and real bridge test, this paper solved the problems such as less test data and field test, insufficient research on mechanism, and so on.
