摘要
从历史诸多座吊桥塌坍事故中汲取教训,分析吊桥毁桥原因为风速达到颤振临界风速所致,介绍吊桥颤振临界风速的实用计算法,并与实桥风洞试验结果进行了对比。
Analyzing several accidents of suspension bridge collapsing in history,the reason is reaching the level of the flutter critical wind speed.The practical method of calculating the critical speed is introduced and the calculated value is contrasted with the test result in wind tunnel.
