MODELLING AND ANALYSIS OF REINFORCED CONCRETE BEAM UNDER FLEXURE USING ANSYS

Understanding the behaviour of structural components like beam, column and wall during loading is crucial for the development of efficient and safe structures. In this article, the reinforced concrete beam has been modelled and analysed when subjected to two point loads at one third span from each support, using Finite Element Analysis tool, popularly called ANSYS software. The modelled and analysed beam having size 600 mm × 160 mm × 160 mm with 3 numbers of 12 mm diameter bars as main reinforcement, 2 numbers of 8 mm diameter as hanger bars and 8 mm diameter at 100 mm c/c as shear reinforcement. The behaviour of the analysed beam has been observed in terms of the flexural behaviour, crack pattern and displacement for various loading conditions such as 50 kN, 150kN, 250kN, 350kN, 450kN and failure load (690kN).Based on the analysis carried out on the RC beams using ANSYS, it is found that results are more sensitive to mesh size, materials properties, load increments, etc.
