摘　　要：由于鞭鞘效应,轻型钢结构自身的层间位移较大,常常不能满足抗震设计要求。根据这一特点,提出在加层中设置粘弹性-摩擦阻尼器(VFD)支撑,对结构振动进行控制,从而使整体结构满足抗震设防要求的全新控制方法,并对设置粘弹性-摩擦阻尼器(VFD)支撑的轻型钢加层砌体结构进行了地震反应时程分析。The technology of adding stories to masonry buildings with light-steel is an effective method. Due to the whipping effect, the layer displacements of light steel structures are generally too large to meet the designing requirement, In this paper, the VFD was set to additional stores to control the vibration of structures so as to meet the requirement of current earthquake-resistant codes of China. A time history analysis method for earthquake-excited steel structure adding stories of hybrid masonry-concrete structures was developed.
