摘要
分析了斜拉桥受力特性及其抗风设计要点,针对斜拉索、桥塔和加劲梁分别研究了其抗风设计问题,包括发生的风振形态、产生机理及影响后果等,并提出了风振控制措施,保证桥梁在风环境下的安全性。
The structural features and wind resistance design essentials on cable-stayed bridges are analyzed. Main issues of wind resistance of stay cables, pylons, and girders are discussed, and their wind-induced vibration morphology, generating mechanism, and effects, etc. are studied, based on which wind vibration measures are recommended, to ensure bridge safety under wind environment.
