中文摘要：
钢管混凝土系杆拱桥通过吊杆将桥道系和拱肋联成整体,共同承受荷载。吊杆的布置形式对结构力学性能有较大的影响。对一座钢管混凝土系杆拱桥进行计算分析,比较了直吊杆和3种斜吊杆布置形式下结构的稳定与动力性能。结果表明,采用斜吊杆可提高系杆拱桥面内刚度,减少地震作用下面内位移。
英文摘要：
CFST tied arch bridge form the integer by the hangers combining the lane and the arch,and bear the loads.The arrangement of hangers plays great roll in the force of such construction.A study is made on the dynamic and stability performance of CFST tied arch bridge under different arrangement of hangers,including vertical hangers and three inclined hangers.The results show the in-place stiffening of the tied arch bridges with inclined hangers can be enhanced and the in-place displacement can be lessened under the earthquake.
