摘要:The objective of this paper is to investigate and compare the flexural properties of steel and basalt fiberreinforced concrete beams with plain M30 grade concrete beams. Experimental and analytical studies are conducted onsteel and basalt fiber reinforced concrete beams reinforced with optimum fiber content, which was obtained by varyingthe fiber dosages from 0%, 0.25%, 0.50%, 0.75%, 1.0% of total volume of concrete. The plain concrete normallycontains numerous micro and macro cracks and it will begin to propagate in the matrix when load is applied. Theaddition of randomly spaced, discontinuous fibres helps in arresting the propagation of cracks and it cannot beachievedby continuous reinforcement. Thus fibers will help to improve the tensile and flexural strength of concrete. This studyincludes two phases, first phase is the comparative study about the shear and flexural behaviour of beams reinforcedwith optimum fiber contentand second phase is the analytical study of these beams using ANSYS 16.1 software. Theoptimum fibercontent for BFRC is 0.75% and for SFRC is 0.5% of total volume of concrete. For shear and flexuralbehaviour of beams, total twelve beams were prepared and tested over an effective span of 700 mm under two-pointloading. The beams were designed as balanced-section. The values obtained from experimental and analytical studieswhere comparable for all the beams. Hence the analytical studies where extended for the full scaled beam elements.
