The effect of fibers on concrete stress and computing the mean crack width

One of the most important characteristics of steel fiber in concrete is to resist against crack propagation and increasing the concrete shear resistance. More than 100 years age, the use of fiber in concrete has been started and from that then on its usage increase in the different type of fiber and also in different part such as the airport runways, bridge deck, dams, industrial floors.In the concrete, fibers by creating bridges through cracks provide further resistance against crack development. Therefore, steel fibers in the reinforcement concrete changed the behavior from brittle to ductile and decrease shear failure. In this study, try to investigate stress of concrete in the presents of steel fibers and using fibers instant of stirrups
