高层建筑驰振临界风速研究

Critical Wind-velocity of Galloping Instability on Tall Buildings

通过对横风向非线性随机振动方程的研究 ,得出可能发生失稳的临界风速公式 ,并对不同截面的结构进行了讨论。

Tall-buildings may produce across-instability induced by flow, it means galloping oscillation. This article will give the formula of the critical wind-velocity by analysing the nonliner equation of random vibration.
