[提要] 為了研究以冷彎薄壁焊接型鋼構件為主要受力構件的多層及中高層鋼框架結構梁柱節(jié)點受力、變形性能及破壞特點，對兩個鋼種(Q235和lOPCu-Re)、三種柱壁厚的梁柱節(jié)點進行了反復循環(huán)荷載作用下的試驗。介紹了試驗情況，分析了試驗結果。
[關鍵詞] 冷彎薄壁焊接型鋼 梁柱節(jié)點 反復荷載 變形 局部屈曲Beam-column joint connected with thin-walled cold-fonned steel members used in middle rise building stmctures is studied. In order to study the properties of this kind of beam-column joints under the low reversed cyclic loading, such as failure state models, defonnability, ductility energy dissipation, stifirness reduction, the low reversed cyclic loading tests of 6 beam-column joints have been performed with two types of steel (Q235 and lOPCu-Re), three kinds of column wall tluckness, and the results of tests and the discussion are presented.
Keywords: welded cold-formed steel; beam-column joint; reversed loading; defonnability; local bucklinS;
