Paper Details

—Self-compacting concrete is a highly-workable concrete. It compacts under its own weight without anyvibration or impact; While, Fiber reinforced concrete (FRC) is a concrete in which small and discontinuous fibers arespread uniformly. The addition of fibers into concrete mass can dramatically change properties of concrete. The finiteelement modeling and analysis of Self Compacting Concrete beam subjected to three point bending load is done inANSYS Workbench 17.2.This paper analyzed the effect of fiber addition on rheological properties and fracture energy of self compactingconcrete. Rheological properties like J Ring, U Box, L Box are determined as per EFNARC standards. Fracture energy(GF) measured using the three-point bending test on pre-notched beams prescribed by RILEM recommendations. Gradeof concrete used is M40 for the beam. The beam is of overall dimension of 430×150×100 mm. The beam is studied forthe ultimate load, load-deflection and load-strain behaviour for this case and compared with the experimental values.The result shows that workability of SCC decreases with addition of fibers but fracture energy increases with addition offibers in self compacting concrete. The study also indicates that finite element modeling is properly able to simulate thebehaviour and fracture properties of SCC beam under flexure. The Comparison study shows that the FEA predicts a 10%variation in the deflection studies.
