仿古建筑双枋-柱组合件耗能能力研究

Energy Dissipation on Antique Buildings Dual-Lintel-Column Joint

  • 摘要: 为研究仿古建筑双枋-柱节点的力学特性,结合仿古建筑形制特点,采用钢-混凝土组合结构形式,设计3个该类型试件.通过在枋-柱连接处设置黏滞阻尼器,形成附设黏滞阻尼器的仿古建筑双枋-柱组合件,对其施加荷载形式为正弦波的快速往复循环荷载.基于获得的试验结果,分析各试件的耗能能力及采用钢-混凝土组合结构形式和设置阻尼器对其耗能能力的影响.结果表明:附设阻尼器后,双枋-柱组合件试件滞回曲线较对比试件更为饱满,且其耗能能力显著提升,试件的破坏模式为弯剪型破坏形式.

     

    Abstract: In the report, in order to study the mechanical characteristics of the dual-lintel-column joint of antique buildings, based on the characteristics of the shape system of the antique building, the steel-concrete composite structure was used to design 3 specimens of this type. The viscous dampers were placed on the dual-lintel-column joint, and the dual-lintel-column modular unit with viscous dampers was constructed, on which the rapid reversed cyclic loading was performed with sine-wave. Based on the experiment result, the energy consumption capacity of each specimen, and the effects of the steel-concrete composite structure and viscous dampers were analyzed. The results showed that the hysteresis curve of antique buildings dual-lintel-column joint with viscous damper is fuller than that of the specimen, and whose energy consumption capacity is significantly improved, and the failure mode of the specimen is bending scissor type destruction.
