Abstract:
The influence of steel fiber on reinforced concrete deep beams is investigated in this study. The experimental investigation was set up for the test of 21 reinforced concrete deep beams; with 8 cm width, 39 cm depth and 100 cm length, consisting of plain and 2% steel fiber reinforced concrete. Deep beam specimens comprise of four groups, without steel reinforcement, with longitudinal tensile reinforcement, with longitudinal tensile reinforcement and horizontal web reinforcement, and with longitudinal tensile reinforcement, horizontal web reinforcement and vertical web reinforcement. All deep beams subjected to third-point loading were measured for deflections at midspan. The ultimate load, crack patterns and mode of failure are reported.The results indicated that the ultimate load capacity of deep beams without steel reinforcement increased by 17% for the addition of 2% steel fibers and beams were failed by flexure. For deep beam with longitudinal tensile reinforcement it appeared that ultimate load increased 30% for the addition of 2% steel fibers, while it increased 23% for 2% steel fiber for deep beams with longitudinal tensile reinforcement and horzontal web reinforcement, and all beams with steel reinforcement showed compression strut failure. The results indicated that adding 2% steel fiber could increase ultimate load capacity of deep beams.Steel fiber addition increased the ultimate load capacity of deep beams when used as web reinforcement. Adding steel fiber not only increased the ultimate load but also reduced the cract propagtion and the spacing of the crack at failure. Moreover adding steel fiber could increase toughness and ductile behavior of deep beams.The cost comparison between deep beams with web reinforcement and deep beams with steel fiber as web reinforcement based on the ultimate load capacity of deep beams in this experiment showed that at the same ultimate load capacity the material cost of adding 2% steel fiber was 6.29 times more expensive than using web reinforcement.
