摘要
文章提出了一种新型预压装配式梁柱节点,为改善目前装配式节点耗能性能不足的问题,在节点梁上部设置贯穿梁柱交界面的耗能钢筋,为节点提供额外的耗能性能。但耗能钢筋对节点抗震性能的影响尚不明确,不能达到指导施工的地步。基于此,文章通过实际试验与有限元模拟分析来探究耗能钢筋对此新型节点抗震性能的影响,为实际设计施工提供相关建议。
This paper proposes a new type of pre-compressed fabricated beam-column joint.In order to improve the current insufficient energy consumption of fabricated joints,energy dissipating steel bars that penetrate the beam-column interface are installed on the upper part of the joint beam to provide additional energy dissipation performance for the node.However,the impact of energy-consuming steel bars on the seismic performance of joints is still unclear,and cannot reach the point of guiding construction.Based on this,this paper uses actual tests and finite element simulation analysis to explore the influence of energy-consuming steel bars on the seismic performance of this new joint,and provide relevant suggestions for actual design and construction.
