The work aims to compare the flexural behavior of concrete beam using addition of steel fibers and glass fibers with normal beam in M30 grade concrete and to find the cracks developed in the concrete beam. Experiments include Compression test, Tensile strength and Flexural strength. In this study the performance of fiber reinforced concrete(FRC) beams under two- point loading system is discussed and comparative studies were made with normal mix concrete. In this study, we are casted the cube for 7 days and beam only for 28 days. The percentage addition by mass of cement for steel fiber is 1.5 % and percentage addition by mass of coarse aggregate for glass fiber is 1%. We are going to compare the results of compression test as well as flexural strength to normal concrete through different( 1.5 and 1) percentages. Final results, the comparison of normal beam to addition of fiber reinforced concrete beam, the maximum flexural strength is found in addition of steel fiber in concrete beam.

A simplified finite element model for analysis of the Layered steel fiber beams with the concrete damaged plasticity model has been presented. The numerical simulation of load-deflection curve of layered steel fiber reinforced concrete beam under three-point loads is performed using ABAQUS. The results of simulation are generally in conformance with the experiment. The results of numerical simulation show that layered steel fiber has little contribution to the elastic capacity of concrete beam. But it can improve the ultimate bearing capacity of concrete beam obviously. The bending collapse style of layered steel fiber reinforced concrete beam is different from plain concrete beam evidently with obvious ductile characteristic.
