摘　　要：为研究传统风格建筑钢-混凝土组合结构枋-柱节点及附设黏滞阻尼器的传统风格建筑的力学性能,设计了2组共计6个试件,包括4个附设黏滞阻尼器的传统风格建筑枋-柱试件及2个未附设黏滞阻尼器的对比试件,对其在正弦波动力循环荷载作用下的恢复力特征曲线、骨架曲线、承载力及刚度退化、耗能能力、延性性能等抗震性能指标进行研究。结果表明:采用钢-混凝土组合结构的传统风格建筑抗震性能优于普通混凝土的传统风格建筑;附设黏滞阻尼器可较大幅度提升传统风格建筑抵御外荷载的能力及耗能能力,结构的整体抗震性能有大幅改善,黏滞阻尼器可在一定程度上抑制试件的刚度退化速率;附设黏滞阻尼器对双枋-柱节点试件抗震性能的改善程度高于单枋-柱节点试件。对试件采用多个地震损伤模型进行评估的结果表明,Park-Ang与Banon损伤模型可较好地反映试验试件的损伤演化规律,可用于对该类型构件损伤规律的表征。研究结果可为传统风格建筑的进一步研究及工程设计提供有益参考。For Chinese traditional style structure with lintel-column joint of steel and composite structures,a research is conducted to analyze its mechanical behavior with and without viscous damper.Six specimens are tested under dynamic experimental,including four specimens with viscous damper and two specimens without viscous damper.The mechanical performances,such as the horizontal load-displacement curves and skeleton curves,load carrying capacity,degradation of strength and stiffness,energy dissipation and ductility of the lintel-column joints are analyzed.The results indicate that seismic behavior of Chinese traditional style structure with lintel-column joint of steel and composite structures is superior to Chinese traditional style structure with lintel-column joint of concrete structures;the load-bearing capacity and dissipation energy capacity of specimens with viscous damper are superior to that of specimens without viscous damper;the seismic performances of specimens with viscous damper are improved significantly.The extent of seismic performance impact of the viscous damper is different for dual-lintelcolumn joints and lintel-column joints,and the former is higher than the latter.Descending phase of skeleton curves with viscous damper are smoother,and stiffness deterioration rate is to some degree to be controlled.A series of damage models are used to evaluate the whole damage process of 6 specimens,and the results show that the damage curve of Park-Ang model and Banon model tally with earthquake damage evolution rule for the Chinese traditional style structure.The results and proposals not only have benefits to further development for Chinese traditional style structure,but also has the reference value to the design,construction and research of Chinese traditional style structure.
