[提要] 鋼筋混凝土梁與鋼管混凝土柱節(jié)點受力性能是影響鋼管混凝土柱結(jié)構(gòu)應(yīng)用的最關(guān)鍵問題。針對某電信樞紐中心的工程實踐提出了穿心暗牛腿+環(huán)梁的新型節(jié)點構(gòu)造形式，對其依據(jù)相似原理進行了靜載及反復(fù)荷載下的節(jié)點模型試驗研究。結(jié)果表明，該節(jié)點傳力路線明確、合理，受力性能較好。根據(jù)試驗結(jié)果改進后的新型節(jié)點已用于工程實踐。

A new type of steel tube confined concrete joint, put forward to solve the difficulty applied in a high-rise building, is tested and researched under monotonic and reverse load. The tested result shows that the new type joint is working well and reliable to capacity.
