Analysis of Steel Fibre Reinforced Concrete Beam without Conventional Shear Reinforcement
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
In recent times 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. The purpose of this project was to investigate the shear strength of steel fibre reinforced concrete beams with and without shear reinforcement. Fibre volume fraction is varied as 1%, 2%, 3%, 4% & 5%. The main variable investigated in addition to the effect of steel fibres, was the influence of a possible size effect, Hence beams of 3 dimensions were modelled and analysed 200x250x1500mm, 200x500x3600mm and 300x700x6000mm. Analyse of the results indicate some favourable aspects concerning the use of steel fibres as shear reinforcement in concrete beams. The project focuses in the design and analysis using the software ANSYS 15, for an alternative steel reinforcement with better or equivalent performance.
