  • Based on bending performance experiment of three groups beams with fifteen test components,whose recycled coarse aggregate replacement rate were different,it was the article analyzed the effect of recycled aggregate replacement ratio on RAC beams meeting the linear plane assumption,deflection,crack width and limit carrying capacity. Meantime the applicability of recycled concrete beams bending limit carrying capacity byCode for Design of Concrete Structures(GB 500102002) was discussed. The research indicated that under the same loads,the appearance of crack on the recycled concrete beams was previous while the width of crack was larger on recycled concrete beams and recycled concrete beams degraded rapidly in stiffness as well. The average strain measured on cross-section could meet the requirement of the plane section assumption. The computational results of recycled concrete beams bending limit carrying capacity by Code for Design of Concrete Structures were feasible,but the formula of GB 500102002 was not comprehensive. It was introduced a kind of suggested formula and adjustment coefficient,which could help to solve related calculation problem and was proved to be effective.
