摘要
目前,抗风问题已经成为决定大跨度桥梁结构安全性的控制因素。针对颤振、驰振、抖振和涡振这4种桥梁风致振动形式,分析了大跨度桥梁的风致振动情况,研究了此类问题的抗风措施。
At present,wind resistance has become a controlling factor that determines the safety of long-span bridge structures.The wind-induced vibration of long-span bridges including flutter,galloping,buffeting and vortex have been analyzed and wind resistance measures for such issues have been studied in this paper.
