摘要
针对传统风格建筑双枋-柱节点抗震性能较差的问题,将其与黏滞阻尼器相结合以提升其抗震性能。为了研究该类型节点的抗震性能,共设计3个传统风格建筑双枋-柱节点,包括2个设置阻尼器的试件及1个对比试件,并对其进行了施加快速谐波荷载的试验。结果表明,附设黏滞阻尼器试件的力学性能明显高于对比试件,滞回曲线更加饱满,耗能能力及延性性能优于对比试件,刚度及强度退化慢于对比试件,表明将黏滞阻尼器与传统风格建筑相结合可显著提高其力学性能。
Aiming at the problem that the seismic behavior of the dual-lintel-column joint of traditional style architecture is poor,a new kind of damping joint was developed by installing viscous dampers on the dual-lintel-column joints in traditional style architecture to enhance the anti-seismic property.Three specimens were tested under harmonic wave dynamic cyclic loading,two of them were joints with viscous damper,and the remaining one had no viscous damper installed for comparison.The results show that the mechanical properties of the joints with viscous damper are significantly better than those of comparing specimen.The hysteretic curve of the joint with viscous damper is plump,the ability of energy dissipation and ductility of the joint with viscous damper are superior to those of the joints without damper,the stiffness and strength degradations are slower than those of comparing specimen,showing that the dual-lintel-column joint in traditional style building with viscous damper has excellent seismic performance.
