摘要

This paper presents experimental and analytical investigations on concrete beams reinforced with basalt fiber reinforced polymer(BFRP)and steel fibers without stirrups.Independent behaviour of BFRP reinforced beams and steel fiber reinforced beams were evaluated and the effect of combining BFRP bars and steel fiber was investigated in detail.It is found that combining s teel fibers with BFRP could change the shear failure of BFRP reinforced beam to flexural failure.Further,the existing analytical models were reviewed and compared to predict the shear strength of both FRP reinforced and steel fiber reinforced beams.Based on the review,the appropriate model was chosen and modified to predict the shear strength of BFRP reinforced beam along with steel fibers.
