Bridges are generally used to cross a stream or a river. Which are used for different purposes such as, if it is used to cross cycles and animals, then it is called as foot bridges. If it used for highway traffic then it is called Highway Bridge, or if it is used to carry railway loading then it is called Railway Bridge, Over the above all bridges the cost of railway bridge is more than the other bridges. The project is a study on reliability of the Railway Bridge Truss changes with decrease in area due to corrosion and how reliability varies if steel strength is below than actual (or) its strength reduced due to corrosion. The tension members are analyzed for the design strength due to yielding of gross section and compression members are analyzed for the design strength. The limit state equations are taken from the clause 6.2 and 7.1.2 of IS 800:2007. The reliability analysis is done for the Railway bridge truss of span 39.0m. Reliability of truss members investigated for different combinations using Hasofer –Lind technique and MATLAB software. System reliability was accused considering various levels of reduction in area and the variation of system reliability was calculated.
