(解放軍理工大學(xué)工程兵工程學(xué)院,南京210007)[摘要] 建立理想鋼筋混凝土模型,通過對理想受拉構(gòu)件滑移的理論分析,探討了鋼筋在外荷載F不變的情況下,有效錨固長度l上不同位置處滑移s的變化規(guī)律,提出了應(yīng)滑移ë的概念,建立了滑移s關(guān)于坐標(biāo)x的函數(shù)式。

(Engineering Institute of Engineer Corps, PLA Univ. of Sci. & Tech., Nanjing 210007, China)Abstract: It established the ideal reinforced concrete model, and through the theoretical analysis of slippage in the ideal pulled member, it discussed the change law of the slippage s in different position of the available anchor-hold length l, put forward the concept of strain slippage ë,and established the slip function.
Keywords: steel concrete; bond stress; strain slippage
