【摘要】 钢管混凝土材料在桥梁工程中已经得到了广泛的应用,随着研究的深入展,钢管混凝土拱桥在车辆荷载作用下的振动特性研究也备受关注。以依兰牡丹江钢管混凝土拱桥为例,通过编制程序以及对计算结果的分析,讨论了车速对此桥梁结构的车桥耦合振动的影响,并提出相关意见,为大跨度钢管混凝土拱桥的设计提供参考。更多还原

【Abstract】 The concrete filled steel tube (CFST) material has already got the wide application in the bridge engineering. Along with the development of study, the vibration characteristics of CFST arch bridge with vehicles has attracted great attention. Taking the Yilan-Mudanjiang CFST arch bridge as an example, it discusses the influencing factors of vehicle-speed on vehicle-bridge linking vibration, and gives some suggestions for designs of the CFST arch bridge.更多还原
