Optimization of Pre Cast Post Tensioned Concrete Deck Type Box Girder Bridge

2017 International Journal of Science and Research (IJSR)  
Bridge is a structure which provides passage over an obstacle without obstructing the way beneath. PSC bridges are adopted for span greater than 20 m. In present study a two lane simply supported Box Girder Bridge is designed for moving loads as per Indian Road Congress loadings (IRC:6-2014) prestressed concrete code (IS: 1343-2012) and IRC: 18-2000 specifications. The cable is prestressed with parabolic tendons.Deck slab is designed by working stress method and girder is designed by limit
