钢筋混凝土烟囱涡激振动的分析

Study on Vortex-induced Vibration of Reinforced Concrete Chimneys

提出了一个数值模型,旨在评估圆柱结构受到空气旋涡作用的响应。该模型可以计算结构在低于或大于临界风速下的振幅。最后,对高100 m的钢筋混凝土烟囱进行数值分析,其结果与实验数据高度吻合,验证了它的可行性。

A numerical model is presented to evaluate the response of cylindrical structure subjected to vortex excitation. The model can assess displacement amplitude for wind velocities lower than or greater than the critical wind speed. Finally,the numerical simulation on a 100 m reinforced concrete chimney is given to show the good agreement between experimental and simulated responses.
