Study of Behaviour of Steel Fiber Reinforced Concrete in Deep Beam for Flexure

Abstract

In 21st century, government invested most of the money on construction industry to improve the financial condition of our country. So it is the responsibility of civil engineer to improve the new techniques and researches in construction field. Use of deep beam in construction field saves money as well as increase the strength of structure. Reinforced concrete deep beams have very useful structural application such as piles-caps, water tanks and tall buildings. Addition of steel fibers gives good results to both load carrying capacity and increase the flexural strength of the deep beam.Steel fiber is kind of newly developed reinforced material for concrete widely adopted globally now a days, which features good performance in anti-crack, pressure resistance, anti-abrasion bending toughness, affinity with concrete, reinforcement for construction element component and lengthy service life. Thus by using the steel fiber reinforced deep beam with varying percentage of steel fibers increases the first crack load and the ultimate load which gives the high flexural strength to the structure and achieves economy. This paper includes study of behaviour of steel fiber reinforced concrete in deep beam with advantages, disadvantages, proprties of steel fiber etc.
