Risk of accidents due to fire is more often and has become a common occurrence leading to the loss of lives and property In this regard, the study investigates the effects of fire on concrete members reinforced or strengthened with polypropylene fibers. The amount of spalling and the extent of cracking of concrete can considerably be reduced by use of suitable amount of polypropylene fibers. In this paper, finite element software ANSYS is used for studying the temperature propagation in concrete exposed to elevated temperatures. An attempt will be done to study the impact of fire on reinforced concrete structural components considering a beam member of cross sectional dimensions 230mm × 600mm providing clear cover according to the specifications of fire safety building code. Based on these parametric studies, results including the effects of high temperature on properties of fiber reinforced concrete together with the strength, stiffness, thermal stress, thermal strains under load and heat flux will be obtained by performing the analysis
