Stay cable, which is one of the important components in cable - stayed bridges, is susceptible to environmental excitation because of its small weight, large flexible, low damping, then the various vibration is induced, such as vortex - induced vibration, wake galloping, rain vibration, buffeting as well as parametric - induced vibration etc. in this paper, the vibration property of stay cable has firstly been introduced
斜拉索是斜拉橋的重要承力構件，由於拉索自身的質量輕、柔度大、阻尼小，在外界激勵下，易發生各種振動，包括渦激振、尾流馳振、風雨振、抖振以及參數振動等。 -
As the demand of low weight and high strength for high damping alloys, the composition of aluminum alloys was determined as al - 20 % zn - 6 % si - 0. 4 % mg ( i. e. azsm ) by the orthogonal experiments. furthermore, effects of alloyed elements, the modifying agents and heat - treatment on microstructures, damping capacities and mechanical properties of the azsm alloy were studied. finally, the damping mechanism of the azsm alloy was proposed
根據對高阻尼合金輕質高強的要求，採用正交試驗法確定了具有良好阻尼性能的鋁合金的成分為al - 20 zn - 6 si - 0 . 4 mg （下稱azsm合金） ；探討了合金化、變質和不同熱處理工藝對azsm合金組織、阻尼性能和力學性能的影響；最後提出了azsm合金的室溫阻尼機制。 -
Owing to many unique properties of their own such as light self - weight, large flexibility and low damping, suspension cables often suffer large displacements but small strains each under normal work conditions. cables are also sensitive to dynamic loading with low frequencies such as wind loading
懸索具有質量輕、柔性大、阻尼低等特點，在正常工作情況下多處于大位移、小應變的變形狀態，對低頻荷載如風荷載等十分敏感。 -
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。 -
Stay cable, which is one of the main components in cable - stayed bridges, is susceptible to environmental and traffic excitations because of its flexible, low damping, small weight, then the significant vibration is induced. the accurate analysis of both the static and dynamic is very import for the design of cables in cable - stayed bridges
斜拉索是斜拉橋的主要受力構件之一，由於其大柔度、小質量和小阻尼等特點，極易發生振動，準確分析斜拉索的靜、動力特性並進行振動控制是斜拉橋設計的重要工作之一。
