Bending Mechanism

In this study, the effect of the change of stirrup ratio and polypropylene (PP) fiber ratio on the behavior of reinforced concrete beams was investigated. The variables of this study consisting of without stirrup, spacing up to 20 %, 40 % and 80 % of beam depth as stirrup spacing and 0.125 % and 0.500 % of the weight of reinforced concrete beam were used as PP fiber ratios. In the context of experimental study, 1/2 scaled 12 reinforced concrete beams were tested with 4-point bending mechanism. In the light of the obtained data, the load-displacement, stiffness and energy absorption graphs were plotted. The results were interpreted comparatively. According to the results, it is observed that the PP fiber additive significantly changed the behavior of the reinforced concrete beams, and the fiber effect decreased in proportion to the increase of the stirrup rate. It has been observed that the cracks spread more to the beam surfaces with the increase of PP fibers. In addition, the increase in the fiber ratio especially in the non-stirrup beams increases the bending capacity.
