A suspension bridge project is taken as an example, in which the evolution ofcriticalwindspeedofflutter during bridge erection is studied by a multi-mode flutter analysis approach.
以某悬索桥设计方案为工程背景,应用多模态颤振分析方法,分析了该桥架设阶段颤振临界风速的发展趋势。

When the head's shape or width of central slot is unsuitable, central slot decreases criticalflutterwindspeed instead of increasing it.
当头部形状或开槽宽度不合适时,中间开槽不但不能提高颤振临界风速,反而降低了断面的颤振稳定性。

Flutter derivatives play very important roles for determining the fluttercriticalwindspeed and buffeting responses of long-span Bridges.
