摘要
采用谐波叠加法对高度为950 m的超高耸烟囱进行了风速时程模拟,并对烟囱进行了瞬态动力学计算,得到了烟囱风振响应,最后计算了烟囱的位移风振系数,结果表明:西缪谱在350 m高度范围内适用于高耸结构,烟囱的风振系数随高度增大而增大。
Wind process simulation was conducted using harmonic superposition method for a 950 m super-high chimney. Transient dynamic calculation was carried out and wind-induced responses was obtained. Wind vibration displacement coefficient of the chimney was calculated at last. The result shows that Simiu was suitable for the high-rise structure within 350 m, wind vibration coefficient of the chimney increases with the height.
