The tow tensile strength of concrete is overcome either by reinforcing it or by prestressing. Both these methods have certain advantages and disadvantages, and one must be very careful with choosing one these two by taking into consideration the structural requirements and economics of the given problem. The common construction material for residential and commercial buildings and other allied structures is still reinforced concrete, though the prestressed concrete is better in structural behavior, durability, ductility, deformability and economy. The aim of present work is to compare the flexure behavior of the reinforced concrete and prestressed concrete beams and finding out the suitability of each. Results show that overall flexural behavior of prestressed concrete beam is very good in all aspect compared to reinforced concrete beam. In this paper analyzed the RCC &PSC beams against the different parameters. We studied the analysis of prestressed concrete beams more effective as compared to equivalent reinforcement concrete beams in flexure. There is a very good understand all aspect of prestressed concrete beam better than as compared to reinforced concrete beam in
