Extended Finite Element Analysis of Creep Behaviour of Steel Fibre Reinforced High Strength Concrete Beam: A Review

Abstract

Structural behaviour of steel fibre reinforced concrete members depends on different parameters such as aspect ratio of fibre, the geometrical shape of fibre and placement of fibre in concrete. Incorporation of fibres in concrete has helped in arresting cracks in concrete and enhancing its capacity. Materials like steel, glass and organic polymers are used to produce fibres suitable for reinforcing concrete. During construction of complex structure first task is to identify the appropriate fibre and its effects on structures. As per the requirement of structure we have to select fibre and have to analyse the consequences after implementation such as cracks. Steel fibre usage percentage and aspect ratio two main parameter which must be integrated with concrete. The main objective of this investigation is to determine two prime parameters compressive total creep and tensile total creep of high-strength concrete beams at long term under following conditions of steel fibre dosage and steel fibre aspect ratio.
