【摘要】 在地震作用下,被动控制装置往往会因为过度变形而失去其隔震功能。磁流变(MR)阻尼器是一种在结构控制领域中表现出巨大应用潜力的半主动控制装置。在房屋建筑基础设置磁流变阻尼器对结构进行振动控制。算例结果表明,MR阻尼器可以有效减小上部结构的地震反应。更多还原

【Abstract】 In the seismic,passive control devices may lose its function of isolation because of excessive deformation.Magnetorheological(MR) Damper is a kind of semi-active control device,which shows immense potential in the field of structural vibration control.In this paper MR damper is located in the basis of structure for vibration control.The results illustrate that MR damper can reduce the earthquake response of upper structure.更多还原
