According to the geometrical characteristics of the surface on the deformed bars, considering the interfacial properties of the corrosion reinforcement and concrete, such as the microscopic mechanics model of corroded reinforcement ribs, the deterioration of ribs on the bearing surface of the deformed bars after corrosion and the effect of corrosion products of corrosion reinforced bar on the bond strength, and analyzing the distribution and interaction of the forces on the surface of the corrosion reinforcement and concrete, the calculation expressions of the bond strength between corroded deformed bars and concrete with and without transverse steel are established
從變形鋼筋的表面幾何特徵出發，考慮了鋼筋銹蝕后鋼筋與混凝土接觸面的特徵，例如鋼筋橫肋在銹蝕狀態下的細觀力學模型，鋼筋銹蝕后鋼筋橫肋高度的變化和銹蝕產物的生成對粘結力的影響。通過分析接觸面上各種力的分佈形式及相互關系，建立了有橫向鋼筋和無橫向鋼筋約束作用下，鋼筋與混凝土之間粘結力的計算表達式，且與相關文獻的結果進行了比較。 -

Abstract : it is a difficult problem to arrange a lot of deformed bars in a narrow section. in foreign codes, it is solved with abreast - arranging deformed bars, but there not be definite answer about influence that the abreast - arranging deformed barsto bearing capacity. in our country, the research about abreast - arranged deformed bars began from the first 1980s. some achievements have been gained from studies about anchor performance. but study about beams bearing capacity and rigidity is not enough. the experiments of 10 beams using abreast - arranged deformed bars and 3 contrast ones are done. the influence that the abreast - arranging deformed bars to bearing capacity of beams is analyzed. three points of division loading have been adopted. the results prove that the bearing capacity of beams decrease by using abreast - arranged deformed bars at a degree from 10 % to 15 %. through statistical analysis, format on bearing capacity of abreast - arranged beams is recommended and reliability of format is analyzed
文摘:在較小截面內單根排列鋼筋比較困難，國外規范大都採用並筋解決，但對並筋后對承載力的影響未作明確規定，我國並筋梁的承載力和剛度研究較少.通過對10根並筋梁和3根對照梁的受彎承載力的試驗，分析並筋對梁的受彎承載力的影響，試驗採用三分點加載，結果表明，與對照梁相比，並筋梁的受彎承載力有所降低，降幅在10 % 15 %之間，通過統計分析，給出了並筋梁受彎承載力的建議公式，並對建議公式進行了可靠度分析 -
