To　overcome　the　existing　problems　of　bamboo　reinforced　concrete　structure,　several　processing　methods　are　proposed　to　improve　the　performance　of　bamboo　bar.　Experiments　on　twelve　flexural　members,　including　eleven　bamboo　reinforced　concrete　beams　and　one　steel　reinforced　concrete　beam,　is　carried　out.　The　mechanical　properties,　failure　modes　and　influential　factors　of　flexural　beams　with　different　processing　methods　and　reinforcement　ratios　are　studied.　The　results　show　that:　bamboo　could　improve　effectively　the　flexural　capacity　of　concrete　beam,　and　the　effective　bonding　between　bamboo　reinforcement　and　concrete　could　be　achieved　if　the　bamboo　is　processed　by　proper　methods.　Moreover,　the　plane-section　assumption　can　be　used　for　bearing　capacity　calculation　of　bamboo　reinforced　concrete　beams.　The　failure　mode　of　bamboo　reinforced　concrete　beams　is　brittle　fracture　and　the　detailed　fracture　pattern　is　related　to　reinforcement　ratios.　©　2015,　China　National　Publications　Import　and　Export　(Group)　Corporation.　All　right　reserved.
