【摘要】 我国目前建造的系杆拱桥以竖直拱面和垂直吊杆为主流形式,本文通过对比研究,系统探讨了系杆拱桥的拱肋及吊杆的结构形式变化对系杆拱桥动力特性及地震响应的影响,基于结构动力特性及抗震性能对其拱肋及吊杆形式的选择提出了合理建议,对于桥梁结构选型具有指导意义。更多还原

【Abstract】 At present, tied-arch bridge with vertical arch-planes and vertic al hangers is a commonly used structural formation in China. By comparison, the in fluence of the structural formation (including both the vertical and inclined co nfigurations) to the dynamic characteristic and seismic response of tied-arch b ridges are systematically studied in this paper. Rational design proposals for t he structural formation of tied-arch bridges are discussed based on their dynam ic and seismic behaviors, which can serve as a design aid.更多还原
