This paper describes three tests on small scale, transversely stiffened plate girder. The objective of the test was to observe collapse mechanism and to study post buckling behavior i.e.in particular to investigate the behavior of the transverse web stiffeners. A problem was selected to choose the dimensions and loads of the plate girder and design can be solved according to clauses of Indian Standers 800-2007. Model analysis technique was used to reduce the dimensions and loads of actual structure. Accordingly three small scale plate girder models were constructed with varying number of stiffeners and with constant dimensions of web, flange and stiffeners. The main objective of this experimental study was to study post buckling behavior. The observation given should facilitate future development of improved method of stiffeners.
