?。? 長安大學(xué)建筑工程學(xué)院 西安710061; 2 西安建筑科技大學(xué)710055)[提要] 提出了鋼管混凝土結(jié)構(gòu)的新型節(jié)點,這種節(jié)點將鋼管混凝土柱的鋼管在節(jié)點區(qū)間斷,用節(jié)點區(qū)密排環(huán)形鋼箍、豎向短筋和芯鋼管來保證鋼管混凝土柱在節(jié)點的連續(xù)性,梁中的縱筋在節(jié)點中連續(xù),梁與節(jié)點區(qū)混凝土成為一體,能可靠傳遞粱中的彎矩、剪力及軸力;通過三個節(jié)點模型試驗結(jié)果驗證了新型節(jié)點的構(gòu)思在概念上是正確的,試件的梁、柱破壞先于節(jié)點。主要分析了試驗現(xiàn)象、破壞機理,提出有待深入研究的問題。
[關(guān)鍵詞] 鋼管混凝土 梁柱節(jié)點 節(jié)點構(gòu)造 芯鋼管 試驗研究 受力分析 模型設(shè)計A new type of column-beam joint of concrete filled steel tubular( CFST)is presented. In the joint zone, the column of CFST is disconnected. The ring and vertical short steel bars, which are closely packed in the joint zone and the core steel tube, can keep a good feature of continuity of CFST in the joint zone. The three models experiment confirms that the failure of the beam and column is earlier than the joint. The phenomenon of experiment and the mechanism of failure, and the problems of further researching are presented.
