Structural Behaviour Of The Fibre Reinforced Concrete Beams

Abstract

The developments of new materials and production methods have increased within the field of construction. Using suitable fibres and additives in concrete to advance its performance is an important consideration in the construction industry with regard to structural aspects of concrete. Concrete is inherently a brittle material with highly weak post peak behaviour. When adding fibres in to the concrete these fibres act as secondary reinforcement in the concrete structures to restrain crack propagation. This paper presents the study on the effect of different types of fibre on the structural behaviour of Concrete Beam. The modulus of elasticity of concrete with different type of fibres plays an important role in behaviour of concrete. The fibres used are Steel fibre, Polypropylene Fibre, Polyolefin Fibre, Poly-vinyl Alcohol (PVA 150 and PVA 240) with different percentages of fibres of 0.5% and 1% of all fibres.  ANSYS software has been used to analyse and study the behaviour of concrete. The aim of the work is to determine the ultimate strength of beam and to determine actual load deflection curve and crack pattern for ultimate strength of FRC Beam.
