摘　　要：本研究采用时域分析法,基于Davenport风速谱,使用线性滤波法中的自回归模型生成脉动风速时程,与对应楼层的平均风速叠加后转换为风压时程逐层施加到结构上,建立的无控结构、TRC粘弹性阻尼器减振结构和黏滞阻尼器减振结构进行风振响应分析,验证粘弹性阻尼器在小应变动力荷载下的加速度和位移控制效果。In this study,the time domain analysis method,based on the Davenport wind speed spectrum,uses the auto regression(hereinafter referred to as AR)model in the linear filtering method to generate the fluctuating wind speed time history,which is superimposed with the average wind speed of the corresponding floor and converted into the wind pressure time history applied to the structure layer by layer,and the established uncontrolled structure,damping structure with TRC viscoelastic dampers and damping structure with viscoelastic dampers are analyzed for wind vibration response to verify the acceleration and displacement control effect of the viscoelastic damper under small strain dynamic load.
