【摘要】 近年来,人行桥不断向大跨、轻柔和纤细化发展,其中缆索支撑体系桥梁特别是斜拉桥更是得到工程师们的青睐,但人桥共振问题也尤为突出。因此,使用隔振装置、耗能装置以及调谐质量装置来改善人行斜拉桥在这种振动条件下的使用性及安全性是一种经济、安全、有效的手段。更多还原

【Abstract】 In recent years,the pedestrian bridges have been increasingly developing to be large-span,flexibe and slim,of which the bridges with cable supporting system,especially cable-stayed bridges are preferred by engineers,on the other hand,the pedestrian-bridge resonance problem is also highlighted.Therefore,it is economical,safe and effective to improve the usability and security of pedestrian cable-stayed bridges under such resonance by utilizing resonance damping device,energy dissipating device and tuned mass device.更多还原
