摘　　要：目的解决门式刚架节点域设计中存在的问题,为工程施工提供借鉴.方法通过在门式刚架转角处节点域设置斜向加劲肋,与无斜向加劲肋的试件进行对比,研究其受力性能.结果对比荷载位移曲线,当转角外缘受压时,节点域内设置斜向加劲肋的构件承载力最高,比没有设置斜加劲肋的节点域承载力提高了约60%.结论在门式刚架节点域中设置斜向加劲肋,可以提高试件的承载力.当工程中门式刚架转角节点处,梁、柱处于正弯矩作用即转角节点域外翼缘受压时,建议架设斜加劲肋以防止结构失稳.This paper mainly investigates the load capacity of the side panel zone in steel gabled frames by static test of four connections by comparing the panel zone with and without the inclined stiffener. The load displacement curves show that when the outer edge of the corner is subjected to compression, oblique nodes installed within stiffening rib components have the maximum capacity, i. e. 60 % more than those without ramp stiffening rib node. The results reveal that in the gabled frames, the comer node with the inclined stiffening rib can improve the bearing capacity of the specimens. At the comer nodes of the gabled frames, when beams and columns are subjected to compression at the extraterritorial flange corner nodes, the erection of the inclined stiffening rib can prevent structural failure.
