The analysis has analysed by STAAD PRO softwareīridges are the most costly components of a road transportation network. Losses of stress due to friction, anchorage slip, elastic shortening concrete & relaxation of stress in steel are also considered. The members are designed for maximum shear forces & bending moment. The present work was accepted out to exterior girder of span 28.2 m, width 12.5 m and with thickness of slab as 0.225m. The bridge deck is analysed by grillage analysis. Analysis of proposal of prestressed concrete bridges are carried out using relevant IRC codes and IS codes. In this work, an attempt is made to provide advise on grillage idealisation of the structure, as well as background information. The grillage analysis method for analysing bridge structures has been in use. For use of prestress girder type bridges become popular for the reason that of its stability, economy, serviceability, aesthetic appearance and structural competence. Bridges remain the key components in any road network for infrastructure development.
