摘　　要：为提高传统风格建筑混凝土梁柱组合件的抗震性能,将其与黏滞阻尼器相结合,形成附设黏滞阻尼器的传统风格建筑混凝土梁柱组合件。为研究该类型试件力学行为,设计了两组不同构造形式的6个试件,每组包括附设黏滞阻尼器的梁柱组合件及未附设黏滞阻尼器的对比试件,对其进行动力循环加载试验,获得其荷载-位移曲线,并对其耗能能力、延性性能及刚度变化等抗震性能进行分析。分析结果表明:附设黏滞阻尼器的传统风格建筑混凝土梁柱组合件荷载-位移曲线饱满,位移延性及耗能能力优于对比试件。随着控制位移的增大,黏滞阻尼器阻尼力-位移包围的面积逐渐增大,耗能能力逐渐增加,但在试件屈服点处,黏滞阻尼器耗能能力有明显下降,之后,耗能能力稳步提升。In order to improve the seismic performance of concrete beam-column subassemblages in traditional style buildings,a new kind of concrete beam-column subassemblages was proposed by combine concrete beam-column subassemblages with viscous damper. A total of six specimens were tested under dynamic cyclic loading to investigate the mechanical behavior,including four specimens with viscous damper and two specimens without viscous damper.The load-displacement curves of the specimens were obtained. The energy-dissipating capacity,stiffness changing and ductility of the beam-column subassemblages were analyzed. The results indicated that the hysteretic curves of the beam-column subassemblages with viscous damper were plump,the energy dissipation capacity and displacement ductility of the beam-column subassemblages with viscous damper were significantly higher than that of contrast specimens. With the increase of control displacement,the area of hysteresis curve encircled and energy dissipation capacity of viscous damper gradually increased. However, the energy dissipation capacity of viscous damper significantly decreased at the yielding points of the specimens,after that,the energy dissipation capacity of viscous damper was improved.
