The　test　of　section　flexural　performance　of　full-scale　simple　supported　reinforced　concrete　beams　with　different　recycled　coarse　aggregate　and　fine　aggregate　replacement　ratios　were　conducted　to　investigate　the　mechanical　characteristics　and　damage　features　of　normal　section.　In　this　paper,　there　are　seven　reinforced　recycled　aggregate　concrete　specimens　with　the　same　structure　were　involved,　its　sectional　size　is　300　mm　X　200　mm　and　net　span　is　3　000　mm;its　recycled　coarse　aggregate　replacement　ratios　are　0%,33%,66%,100%.respectively　and　recycled　fine　aggregate　replacement　ratios　are　0%,50%,100%,　respectively.　The　test　analyzed　the　effects　of　different　recycled　coarse　and　fine　aggregate　replacement　ratios　on　cracking　load,　yield　load,　ultimate　load,　deflection,　cross-section　strain,　crack　and　damage　process　of　beams　by　a　third-point　one-way　repeated　loading　way.　The　results　show　that　the　recycled　concrete　beams　still　undergo　four　apparent　processes,　i.　e.,　resilience,　cracking,　yielding　and　limiting　when　cross　sections　are　under　stress.　The　average　strain　of　normal　section　conforms　to　plane-section　assumption.　The　damage　process　of　recycled　concrete　beams　is　similar　to　the　normal　ones.　The　ultimate　bearing　capacity　of　recycled　concrete　beams　is　close　to　the　normal　ones　under　the　same　concrete　strength　and　same　reinforcement　ratio.　The　recycled　coarse　aggregate　replacement　ratio　have　little　effect　on　the　bending　performance　of　beams,　while　the　recycled　fine　aggregate　replacement　ratio　have　some　effect　on　the　distribution　of　crack　and　deflection.　©　2017　Science　Press.　All　rights　reserved.
