One of the materials that can replace rebar in reinforced concrete is fiber. Reinforcing the concrete with fibers instead of rebar reduces the weight of the concrete and eliminates the damage caused by corrosion and erosion of the steel. Also By reducing the consumption of steel, we can get closer to making sustainable concrete. reinforcement of concrete structures with fibers is one of the methods to improve the mechanical properties and improve the flexural and tensile performance by which brittle mixtures show somewhat elastic behavior.

One of the materials that can replace rebar in reinforced concrete is fiber. Reinforcing the concrete with fibers instead of rebar reduces the weight of the concrete and eliminates the damage caused by corrosion and erosion of the steel. Also By reducing the consumption of steel, we can get closer to making sustainable concrete. reinforcement of concrete structures with fibers is one of the methods to improve the mechanical properties and improve the flexural and tensile performance by which brittle mixtures show somewhat elastic behavior. In this book, the compressive strength of concretes containing macro synthetic fibers has been studied, and compression samples with percentages of 0-1.5% have been made in the laboratory, and the necessary tests have been performed on them. Finally, we concluded that adding fibers increases the compressive strength of concrete by 1.5%.Also, in Abaqus finite element software, a 3 story concrete frame containing fibers is modeled and subjected to cyclic loading. The use of fibers reduces about 25% of the rebars without reducing the strength.
