Parametric Analysis of Single-Cell Box Girder Bridge

Bridges based on box girders concept are extensively utilized for their cost saving solution for different passages & viaducts that are seen in the present day highway systems. The behavior of box girder bridges is analyzed for stresses in longitudinal and transverse directions. In this paper, analysis of three different box girders has been carried out using SAP2000 as per Indian Road Congress(IRC) provisions for rectangular and trapezoidal sections. The behaviors of box girders with uniform depth and varying widths have been analyzed. A parametric study is conducted for various parameters like bending moments, axial force & shear force using SAP2000.
