摘　　要：为研究附设黏滞阻尼器的传统风格建筑混凝土梁-柱节点地震损伤演化规律,进行6个该类型构件的动力荷载试验,并分别采用位移型、能量型及位移-能量混合型损伤模型对其进行全过程评价,采用Park-Ang模型分析试件黏滞阻尼器型号、试件类型等因素对混凝土传统风格建筑梁柱节点损伤行为的影响。研究结果表明:附设黏滞阻尼器可显著提升传统风格建筑节点的承载能力、延性性能及耗能能力,结构的抗震性能得到较大幅度的提升;Park-Ang损伤模型与Banon损伤模型适用于传统风格建筑节点损伤演化规律的描述,建议对该类型节点的损伤规律表征选用该损伤模型。黏滞阻尼器型号可在一定程度上影响传统风格建筑的损伤演化发展;设计阻尼力大的试件虽然延性有所提高,但受荷过程中累积损伤也较大。To study the earthquake damage evolution rule of the beam-column joint in traditional-style buildings with viscous damper under dynamic cyclic loading,a dynamic loading test was carried out on six specimens.A damage model of displacement type,energy type,and displacement-energy type was used to evaluate the damage process.The results showed that the seismic behavior of the joints in traditional-style buildings with viscous damper is superior to that in buildings without viscous damper.The bearing capacity,ductility performance,and dissipation energy capacity of specimens with viscous damper are superior to those of buildings without viscous damper.The damage curves of the Park-Ang model and the Banon model can describe the earthquake damage evolution rule of the beam-column joint in traditional-style buildings.The type of viscous damper will affect the damage evolution and development of traditional-style buildings to a certain extent.Although the ductility of specimens with large design damping force is improved,the cumulative damage is also large under loading.
