摘要：提出了一种新型减振摇摆结构体系，通过在外附摇摆钢框架与原框架连接节点处设置阻尼器，形成外附耗能摇摆钢框架结构。设计制作了外附耗能摇摆钢框架结构缩尺模型，并对其进行了振动台模拟试验。通过分析结构在不同工况下的动力特性、加速度、位移响应，得到了结构的最大楼层加速度和层间位移减震效果以及阻尼器的耗能情况。结果表明：外附耗能摇摆钢框架结构多节点耗能有效减轻了结构的地震响应，加速度均方根减震系数最高达到49.6%,最大层间位移减震系数达到68%,避免了层间变形集中，使层间变形趋于均匀，提高了框架结构的耗能能力。外附耗能摇摆钢框架结构能够有效减轻震害，具有可更换、方便施工的特点，在建筑物的抗震加固中有着良好的应用前景。

Experimental study on seismic performance of external energy dissipative swing steel frame structure
Abstract: A new type of vibration-reducing and rocking structure system was proposed. By setting dampers at the connection joints between the external energy dissipative swing steel frame and the original frame, the external energy dissipative swing steel frame structure was formed. A scaled model of the external energy dissipative swing steel frame structure was designed and manufactured, and a shaking table simulation test was carried out on it. By analyzing the dynamic characteristics, acceleration and displacement response of the structure under different working conditions, the maximum floor acceleration and inter-story displacement shock absorption effect of the structure and the energy consumption of the damper were obtained. The results show that the multi-joint energy dissipation of the external energy dissipative swing steel frame structure effectively reduces the seismic response of the structure. The acceleration RMS shock absorption coefficient reaches 49.6%, the maximum interlayer displacement shock absorption coefficient reaches 68%. The interlayer deformation concentration is avoided, the interlayer deformation tends to be uniform, and the energy dissipation capacity of the frame structure is improved. The external energy dissipative swing steel frame structure can effectively reduce earthquake damage and has the characteristics of replaceable and convenient construction, and has a good application prospect in seismic reinforcement of buildings.
