（天津大學土木系 300072）[提要] 對12個異形柱（T形、L形和十形）和4個矩形柱的足尺板柱節(jié)點和梁柱節(jié)點試件進行了反復荷載作用下受力過程和破壞特性的試驗研究及分析對比。研究表明：在板的正常配筋條件下板柱節(jié)點是不會破壞的；四種截面形式柱中L形截面柱節(jié)點的承載力是最低的。通過試驗和非線性有限元分析，對異形柱框架梁柱節(jié)點的強度提出了計算公式，計算結(jié)果和試驗結(jié)果吻合較好。
[關(guān)鍵詞] 異形柱框架節(jié)點 反復荷載 節(jié)點強度Experimental research and analytical comparison of force-bearing process and failure behavior of 12 R.C. beam-special shaped (T, L and +)column joints as well as 4 R:C. beam-rectangular shaped column joints and panel-special shaped column joints under repeated loading are achieved. The research shows that the panel-special shaped column joints of normal reinforcement will not be failure, and among four types of columns, bearing capacity of L shaped column joints is the lowest. The calculation formulas for determination of shear strength for special shaped column joints are proposed. The calculational and experimental results are good agreement.
Keywords: frame joint; special shaped column; repeated loading; shear strength of joint
