arch stay
解釋
拱的加勁桿-
Accordingly, the problem of dynamical, such as seismic response, wind induced vibration, coupled dynamical vibration between bridge and vehicle should not be ignored. especially, stay cable, which is one of the main components in cable - stayed cfst arch bridge, is susceptible to environment and traffic excitations because of its flexible, low damping small weight, then the significant vibration is induced. the accurate analysis of the dynamic characteristics of cable - stayed cfst arch bridge is very important for the design of this type bridge
大跨斜拉鋼管混凝土拱橋作為一種新型的組合結構橋梁，由於結合了斜拉橋和拱橋的優點，已經運用到實際工程中，但其理論研究才剛剛起步，大跨斜拉拱橋與大跨拱橋、斜拉橋一樣，是一種柔性結構，應該重視其動力問題，地震、風振、車振等動力問題是該類橋梁所無法迴避的，尤其是斜拉拱橋的主要承力構件之一的斜拉索，由於其大柔度、小質量和小阻尼等特點，極易發生振動，準確分析斜拉拱橋及斜拉索的動力特性是斜拉拱橋設計的重要工作之一。
