Abstract: The structural action of a beam is predominantly bending, with other effects such as shear, bending and buckling also being present. The corrugated steel plate is a widely used structural element in many fields of applications because of its favourable properties. Present study aimed to investigate bending and buckling performance of plate girder with flat web section and corrugated web section of different corrugation pattern namely triangular and rectangular. The finite element analysis of plate girder is carried out using SAP2000. For present study total twenty one models were obtained for analysis. Thickness of web of all models varied from 1mm to 3mm incrementally at 1mm; under corrugated web of triangular pattern different angles (300, 450 and 600) are studied and under corrugated web of rectangular pattern different corrugation width (100mm, 200mm and 400mm) are studied. Results obtained from analysis are then compared with plate girder with flat web section of uniform depth. It is observed that plate girder with triangular web section and rectangular web section has higher stiffness about minor axis and has lower stiffness about major axis when compared with plate girder with flat web section. Maximum buckling strength is observed in plate girder with triangular web section and rectangular web section when compared with flat web section.
