摘　　要：结合总高438.6 m的某超高层建筑,采用现在广泛流行的线性滤波法中的AR自回归模型,模拟了该结构具有随机性、时间相关性、空间相关性的28条顺风向脉动风荷载时程样本,并对结构进行了风振响应分析。Combined with a high-rise building with 438.6 meters tall. By using the Auto-Regressive（AR） model, 28 samples of fluctuating wind load are simulated which has randomly, stochastically time and space correlativity. Then, the wind-induced vibration response of the structrure is calculated.

关 键 词：高层建筑 风荷载 AR模型 风振响应分析
