摘　　要：提出一种带摩擦耗能螺栓的梁柱节点,通过开展试验研究与有限元分析,探讨该类节点在往复荷载作用下的滞回性能以及节点域的变形特征。详细介绍了该类节点的有限元建模过程和参数设置,通过对比试验与有限元分析结果,发现数值分析较好地模拟了节点的整个受力和变形过程,验证了有限元分析的可靠性。综合研究结果表明:所提出的梁柱节点能够利用摩擦型螺栓的滑移提高节点的耗能能力,有效减少梁、柱主体构件的损伤,同时预应力筋提供了结构的自复位能力,可以通过更换摩擦型螺栓实现结构功能的快速恢复。A beam-column joint with friction energy dissipation bolts was proposed. The experimental study and finite element analysis were carried out to investigate the hysteretic characteristics and the deformation patterns of the joint under quasi-static loading. The finite element modeling process and parameters settings were introduced in detail.Through the comparison of the experimental and finite element analytical results,it was found that a good agreement was achieved,which validated the reliability of the whole load-deformation process simulation by using finite element analysis. The studies showed that the proposed beam and column joint with the friction bolts could improve the energy dissipation capacity and effectively reduced the damage of the beams,columns and other main members. Meanwhile,the pre-stressed tendons could provide the self-centering ability of the structure,and the structural function could be quickly restored after damage by replacing the friction bolts.
