FEA of Steel Fibre Reinforced Beam Curved in Plan

In the era of modern construction techniques and the increasing demand of aesthetic appearance of structure, beams curved in plan have found significant utilization within bridge structures, balconies, dome rounded corner buildings, water tanks etc. Concrete, the most consumable construction material has various advantages, however, one of the limitations of concrete is its low tensile strength. To compensate this limitation, fibres are added to concrete. The demand of steel fibre in construction technique is increasing as steel fibre gives high tensile strength and ductility. By adding steel fibre in reinforced concrete beam, the ultimate strength of beam can be enhanced. Finite Element Method or Finite Element Analysis is a tool used to simulate the beam in virtual environment. The objective of this study is to analyse the flexure behaviour of beam curved in plan. The curved beam with subtended angle of 450 and 600 containing fibre fraction of 0%, 0.5% and 1% by volume of concrete is used. To validate the curved beams modelled in Abaqus software, the experimental test is performed on three simply supported straight beams and same beams are analysed in Abaqus software. The straight beam contained the same fraction of 0%, 0.5% and 1% by volume of concrete.
