ASSESSMENT OF ENERGY ABSORPTION OF STEEL, POLYPROPYLENE AND HYBRID FIBER REINFORCED CONCRETE PRISMS USINGGRAPH SOFTWARE

This paper presents a description on the growth of a simple form for calculating the energy absorption by steel, polypropylene and hybrid fibers. Three major mechanism were recognized as contributing to the energy lost by the projectile during ballistic impact, namely, the energy absorbed in tensile failure of the compound, the energy converted into elastic deformation of the combined and the energy converted into the kinetic energy of the moving portion of the compound. Themainrequirementsofearthquakeresistantstructuresaregoodductilityandenergyabso rptioncapacity.Fiberreinforcedconcretepossesseshigh modulus of rupture and tensile strength, improved ductility, high energy absorption compared to normal concrete against seismic loads. The purpose of this paper is to analyze the energy absorption capacity of steel, polypropylene and hybrid fibers. The energy absorption capacity was quantified for axial loading. Based on the results of the investigational study, it can be identified that the addition of 4% by volume of steel fibres are the best result on the modulus of rupture and energy absorption capacity of the prisms beam. The present study has been taken up for estimating different types of concrete. Emphasis has been laid on the strength and deformation properties of reinforced concrete beams. This paper presents the results of an experimental investigation carried out on 4 different types reinforced concrete prisms beams of dimension, (150 × 150 ×700) mm. The prisms beam be tested under one-point loading. The results expression that the modulus of rupture properties of concrete matrix is considerably enhanced by the adding of steel, polypropylene and hybrid fibers.
