| Abstract | ||||
| This research aimed to study the bending behavior of self-compacting concrete (SCC) beams reinforced with steel fiber and B500 ribbed reinforcing bar. The studied variables were four: cracking patterns and failure mode, effect of main reinforcement area, effect of rebar grades, and effect of fiber content. Six rectangular beams of cross section of size 100×200 mm and a length of 2000 mm were casted and tested under four-point bending. One beam was used as a control beam without steel fibers, while the other five beams were casted using steel fibers. The steel fiber content was varied from zero to 25 and 50 kg/m3. Three types of rebar main reinforcement were used B500DWR, B500CWR, and B500C-R. According to the experimental results, the tensile strain at failure load ranged from 64,4.7 and 99.2% of that of control beam B1 and the compressive strain at failure load was 76.2 % and 57.1 % of that of beam B1, the control beam. The failure load for beams were 101.5.3 and 106.7 % of that of the control beam B1. Changing the main reinforcement for beams lead to the maximum deflection for beams ranged from 101.5, 109.9, and 81.3% of that of the control beam. | ||||
