摘　　要：针对腹板开孔型梁柱外伸端板连接节点的不足,提出了套管加强型腹板开孔梁柱外伸端板连接节点形式。利用有限元软件ANSYS对这种新型节点的滞回性能进行参数分析,探讨开孔位置、套管半径、套管厚度和套管长度对节点滞回性能的影响。结果表明:套管加强梁腹板开孔梁柱端板连接节点采用合理的细部构造形式具有较高的承载能力,并且能够使梁端塑性铰外移,具有较好的滞回性能。套管加强腹板开孔梁柱端板连接节点更加适用于工程设计及应用。To make up for the shortcomings of beam-to-column end-plate connections with web opening,the paper put forward a new beam-to-column end-plate connections with web opening reinforced by stub tube.The parametric study of the mechanical properties of the new type connection was conducted by using the finite element software ANSYS.Furthermore,the influence of the opening position,tube radius,the stub tube＇s thickness and the stub tube＇s length on the hysteretic behavior was discussed.The results indicated that the beam-to-column end-plate connection with web opening reinforced by stub tube had better bearing capacity,the new connection could move the beam plastic hinge away form the end plate welding zone,and the connection showed excellent hysteretic behavior.The beam-to-column end-plate connection with web opening reinforced by stub tube was more suitable for engineering design and application.
