【摘要】 建筑结构在外部激励下的振动控制一直以来是振动控制领域研究的热点。其中,半主动控制策略包含了被动控制和主动控制的优点,能更有效地提高建筑结构的抗震性能,减轻其在动力作用下的反应及损伤。基于磁流变阻尼器的半主动控制策略也有很大的发展,在实际工程中已有所应用。磁流变阻尼器的主要性能取决于磁流变液成分。综述国内外磁流变阻尼器的研究发展历程,及其在建筑结构减震控制中的应用,展望其在建筑结构减振控制应用中的发展趋势。更多还原

【Abstract】 Vibration control of building structures under external excitation has been the research focus of the field of vibration control.Among them,the semi-active control strategy includes the advantages of passive control and active control,can more effectively improve the seismic performance of the building structure,reducing its injury under the power reaction.Semi-active control strategy based on magnetorheological damper greatly developed,has been applied in practical engineering.Magnetorheological damper performance depends on the composition of the magnetorheological fluid.Reviewing of domestic and foreign research and development of the magnetorheological damper history,and its application in the building structure damping control,looking to the development trend in the building structure vibration control applications.更多还原
