摘　　要：基于基础隔震的理念研究了一种新型摩擦阻尼器与钢筋沥青隔震墩复合作用下的减震效果。通过地震模拟振动台试验研究2层钢框架模型在复合隔震层作用下的加速度和位移反应。通过对试验数据的分析和对比,带摩擦阻尼器钢筋沥青隔震墩有明显的减震效果。未加摩擦阻尼器时加速度折减系数在0.40~0.52,加上摩擦阻尼器后加速度折减系数在0.51~0.76。同时,摩擦阻尼器和钢筋沥青隔震墩施工简便,造价较低,实用性良好,可以较大范围地应用于农村多层房屋结构和工业建筑中。Based on the concept of base isolation,the damping effect of a new type of friction damper combined with reinforced asphalt seismic pier is studied. The acceleration and displacement response of the two-story steel frame model under the composite isolation layer are studied by seismic simulation shaking table test. After the analysis and comparison of the experimental data,reinforced asphalt seismic pier with friction damper has a significant shock absorption effect. The acceleration reduction coefficient is between 0. 40 and 0. 52 when the friction damper is not added,and the acceleration reduction coefficient is between 0. 51 and 0. 76 after adding the friction damper. At the same time,the friction damper and the reinforced asphalt seismic pier have the advantages of simple construction,low cost,good practicability and wide application in rural multi-storey house structure and industrial buildings.
