摘　　要：为研究黏滞阻尼器与装配式钢框架中间柱式连接的整体抗震性能,且跨内不同位置的减震效率,设计出3个足尺的三层装配式钢框架结构:无控结构、柱靠边布置结构和柱居中布置结构,利用振动试验台对其进行测试,对比研究模型结构的地震反应,并采用有限元软件SAP2000进行模拟验证。试验和数值模拟结果均表明:无控结构在地震输入下地震反应较大,对其附设黏滞阻尼器后,地震响应得到有效控制,且柱居中布置结构的附加阻尼比高于柱靠边布置结构,其减震效果更优。In order to study the overall seismic performance of the middle column connection between the viscous damper and the assembled steel frame,and the damping efficiency of different positions in the span,three full-scale three-story assembled steel frame structures are designed:uncontrolled structure,column side arrangement structure and column center arrangement structure.The seismic responses of the model structures are tested by vibration test bench,and the seismic responses of the model structures are compared and verified by finite element software SAP2000.The test and numerical simulation results show that the seismic response of the uncontrolled structure is large under seismic input,and the seismic response is effectively controlled after the viscous damper is attached to the structure.Moreover,the additional damping ratio of the column center arrangement structure are higher than those of the column side arrangement structure,and the damping effect is better.
