摘要

摘要: 为了避免翼缘盖板与楼板相互影响，基于塑性损伤控制和防屈曲设计理念，提出了一种翼缘盖板内置型可恢复功能装配式开洞槽钢梁柱节点，该节点通过翼缘内盖板和槽型腹板连接板连接悬臂梁段和开洞槽钢组合梁段。节点在加强悬臂梁段的同时对翼缘盖板进行了狗骨式削弱处理，有效地将塑性铰转移到翼缘内盖板上。共对4个参数不同的节点算例进行了有限元模拟，主要研究了翼缘盖板厚度、狗骨削弱段宽度和连系螺栓数量等参数对节点承载性能的影响。通过对数值模拟获得的荷载-位移曲线、节点破坏模式、构件应力、螺栓拉力变化等进行分析可知，所提出的新型梁柱节点具有良好的承载能力和塑性转动能力，能将塑性铰外移到可更换的翼缘内盖板上，满足震后通过更换局部构件就可恢复节点使用功能的设计预期；槽型腹板连接板的设置可对节点提供二次强化的效果，有效提高节点的延性。

Abstract: In order to avoid the interaction between flange cover plates and floor, a kind of earthquake-resilient ductility-reinforced prefabricated opening-web steel channel beam-column joint based on the concept of damage control and buckling-restrain was proposed in the paper. Inner flange cover plates and U-shaped web connecting plates were used to connect the cantilever beam and the opening-web steel channel beam. The flange of the cantilever beam was strengthened and the flange cover plates were weakened like dog bone, so the plastic hinge was transferred to the flange cover plates effectively. A total of four examples with different parameters were calculated by finite element method. The influence of the parameters such as the thickness of the flange cover plates, the width of the dog bone weakening section and the number of connecting bolts on the mechanical properties of the joints was mainly studied. By analyzing the load-displacement curves, stress nephogram of joints, stress distribution of components and bolt tension curves obtained by finite element numerical simulation, the paper demonstrated that by setting the relevant parameters reasonably, the earthquake-resilient ductility-reinforced prefabricated opening-web steel channel beam-column joint had good bearing capacity and plastic rotation capacity, and could transfer the plastic hinge outward to the replaceable inner flange cover plates, meeting the design expectation that the joint function could be restored by replacing the local components after the earthquake. U-shaped web connecting plates could produce the effect of secondary reinforcement to the joint and improve the ductility of the joint effectively.
