Effects of different loading conditions on BS460B steel reinforcing bar using Multiphysics modelling technique

Abstract

Nowadays, BS460B bar (steel reinforcing bar) also called as rebar are very useful to strengthen the concrete constructions and gives support to the constructions. In this study five samples of BS460B bars are developed using different loading conditions. This present article shows the simulation performed to investigate the effects of the different loads and corresponding von Mises stresses developed when the load is applied. This modelling and simulation for the BS460B bars using Structural Mechanics Module were performed in the COMSOL Multiphysics 5.5. This present article also investigated the total deflection under gone by the bars under different loading conditions. The effects of different loading conditions were evaluated in terms of the von Mises stresses (principal stresses), and the total displacement developed in the rebar steel. From the obtained results it is observed that on increasing applied load, von Mises stresses increases linearly with the load applied which is presented in the graph.
