Steel Fibre Reinforced Concrete (SFRC) has been very widely used in the structures such as thermal power plants due to its bonding effect, ductility, durability and stability of the structures at high temperatures. The concrete structure when exposed to high temperatures, shows the numerous chemical changes in the concrete which leads to deterioration of the structure. The flexural behaviour of the concrete prism with steel fibre volume fraction of 1.35% and without steel fibre, at room temperature (28°C) and when exposed to elevated temperatures of 150°C, 350°C, 550°C and 750°C for the time period of 1 hour were observed. The Finite Element Analysis was done for the prism, to find the deflection on the plain concrete and steel fibre reinforced concrete when subjected to the same temperatures as mentioned above. The main objective of this study was to decrease the structural element failure when exposed to elevated temperature, which in turn increases the evacuation period of the occupants during fire accidents. © 2019, Fundatia Serban Solacolu.
