8 The present study focuses on understanding the effect of steel fiber dosage on cracking and 9 ductile behavior of prestressed concrete beams (PCB) under flexure using digital image 10 correlation (DIC). Seven prestressed concrete beams were cast and tested under a shear span 11 to depth (a/d) ratio of five to simulate the flexure/flexure-shear dominant behavior. Full field 12 strain measurement with DIC technique was used to understand the effectiveness of steel 13 fibers on the crackdoi:10.14359/51706827 fatcat:h46uhuhrynampbdq3p5wcvlvga
