［摘要］對在門式剛架轉角節(jié)點處設置斜向加勁肋和無斜向加勁肋的試件進行了試驗和有限元分析，對比荷載-位移曲線，轉角節(jié)點處設置斜向加勁肋的構件承載力比沒有設置斜向加勁肋的構件承載力提高了約40%。研究結果表明，在轉角節(jié)點處設置斜向加勁肋可以提高試件的承載力。實際工程中，當外翼緣受拉時，建議在轉角節(jié)點處設置斜向加勁肋，防止結構失穩(wěn)，并能有效改善結構的延性。

Abstract:Static test and finite element analysis of the corner joints with and without the inclined stiffener of gabled frames were introduced The load displacement curves show that the component bearing capacity of corner joints with inclined stiffening rib is enhanced 40% more than that without inclined stiffening rib The results reveal that in the gabled frames, the corner joints with the inclined stiffening rib could improve the bearing capacity of the specimens In practical projects, when the extraterritorial flange is tensioned, the inclined stiffening rib could prevent the structural failure and improve the ductility of the structure effectually.
Keywords:gabled frame; corner joint; full-scale experiment; stiffening rib; finite element analysis
