Abstract：
At home and abroad at present，the research of FRP tendons is mainly concentrated in CFRP tendons，GFRP reinforcement and AFRP reinforcement，and the study of BFRP reinforcement is lacking. In this study，and BFRP concrete beam deflection of BFRP is deduced after cracking of reinforced concrete beam section formula of moment of inertia，considering stress in tension in the process of the players，the effect of using section effective moment of inertia calculation methods of commonly used at home and abroad，combined with BFRP thaws performance indicators，calculated the BFRP reinforced beam deflection，and put forward the BFRP reinforcement beam span ratio based on the deflection control.
