摘要
为确保现有哑铃形钢管混凝土系杆拱桥的安全运行,以某哑铃型钢管混凝土系杆拱桥为例,对这类桥梁进行静载试验。采用有限元软件Midas/civil对桥梁结构进行计算和分析,并与实测的挠度、应力和应变进行对比。研究结果为以后该类型桥梁检测提供参考。
In order to ensure the safe operation of the existing dumbbell-shaped concrete-filled steel tubular tied arch bridge,a dumbbell-type CFST tied arch bridge was taken as an example to carry out static load test on such bridges.In this paper,the finite element software Midas/civil is used to calculate and analyze the bridge structure,and compared with the measured deflection,stress and strain.This paper introduces in detail the current working state of the dumbbell type tied arch bridge,which provides a reference for the future detection of this type of bridge.
