Behaviour of Reinforced Concrete Beam under High Temperature using Finite Element Analysis

Numerous levels of research work have been conducted over the years for the improvement of concrete with newly formed materials and methodologies. In this research work attempted to execute the behaviour of concrete under high temperatures and at different transient levels. The model is experimented with the actual dimension and simulated on Abaqus under the different working load of 40%, 50% and 60% with the ultimate load. In Abaqus software, the exact dimension used in the experimentation is modelled and meshed to find out the solution for each element. The modelled beam is conditioned at transient state analysis and executed for 180minutes (3hrs) on the simulation run with the three different lengths with three faces. Ultimately, the research findings explain that the effect of the transient heating stage under various beam lengths and faces is evaluated. The finding shows, an increment level of effectiveness is made to improve the crack behaviour of concrete when the transient stage is maintained at the temperature of 29°C for the working loads on right and full length and its effective measures on crack behaviour, deflection and rotation are plotted as graphs in the result section respectively.
