摘　　要：将消能减震装置(如黏滞阻尼器)附设在传统风格建筑混凝土双枋-柱节点构件上,形成了一种新型阻尼节点,通过黏滞阻尼器来耗散地震能量以达到减震的目的。为研究该新型阻尼节点的抗震性能,设计了3个试件,包括2个新型阻尼节点试件及1个未安装黏滞阻尼器的对比试件,对其施加正弦波动力循环荷载,观察其受力全过程及破坏特征,分析其破坏模式。在试验基础上,对试件荷载-位移曲线、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及黏滞阻尼器阻尼力-位移曲线进行研究。试验结果表明:附设黏滞阻尼器的新型阻尼节点抵御外荷载的能力明显高于对比试件,滞回曲线更加饱满,骨架曲线的下降段更为平缓,其耗能能力优于未附设黏滞阻尼器的试件,表明将消能减震装置与传统风格建筑相结合可显著提高其力学性能。A new kind of damping joint is developed by installing energy dissipation devices （such as viscous dampers） on the dual lintel-column joints in traditional style buildings to reduce the seismic response and enhance energy dissipation. Three specimens were tested under sine wave dynamic cyclic loading, two of them are new damping joints with viscous damper, and one of them has no viscous damper installed and is for comparison. The loading process and failure patterns were observed. 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 dual lintel-column joints and load-displacement curves of viscous damper were analyzed. The results indicate that the load-bearing capacity of the damping joint is significantly higher than that of the comparing specimen. The hysteretic curve of the damping joint is plump. Descending phase of skeleton curves is smoother. The ability of energy dissipation of the novel damping joint is superior to that of non-controlled specimen, showing that the dual lintel-column joint in traditional style building with viscous damper has excellent seismic behaviors.
