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

Nagaraj Nayak | Dr. S. S. Bhavikatti


Abstract: 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 (IRC6-2014) 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 state method. A computer program is developed in C- programming language to design the deck slab and PSC Box-girder. Optimization is carried out by using sequential linear programming with improved move limit method.
