Bridge construction today has achieved a worldwide level of importance. Bridges are the key elements in any road network and use of prestress girder type bridges gaining popularity in bridge engineering fraternity because of its better stability, serviceability, economy, aesthetic appearance and structural efficiency. In this thesis analysis and design of prestressed concrete bridges (Deck Slab, T-Girder and Box Girder) are carried out using IRC:112-2011. The unified concrete code (IRC:112) published by the Indian Road Congress in November 2011 combining the code for reinforced concrete and prestressed concrete structures represents a new generation code, which is significantly different as compared to previous codes (i.e. IRC:21 for RCC structures and IRC:18 for PSC structures). IRC:21 and IRC:18 stands withdrawn, with the publication of IRC:112. The fundamental difference between IRC:112 and old codes is that IRC:112 based on limit state theory while the previous codes were based on working stress design philosophy.
