[提要] 從連續(xù)梁延性定義出發(fā),論述了鋼筋混凝土連續(xù)梁位移延性的計算方法,并推導出相應的計算公式,同時給出了判別鋼筋混凝土連續(xù)梁屈服和形成機構(gòu)的方法。
[關鍵詞] 鋼筋混凝土連續(xù)梁 位移延性 塑性鉸 機構(gòu)Starting from the definition of continuous beam ductility, this article describes the calculation methord for displacement ductility of reinforced concrete beam. The related calculation formula is deducted. Meanwhile the methord to distinguish the reinforced concrete continuous beam yielding from the formative mechanism is given.
Keywords: reinforced concrete; continuous beam; displacement ductility; plasticity hinge, mechanism.
