Pre-stressed concrete box girders have become increasingly popular as bridge superstructures because of its high torsional stiffness and strength. Most of the study is concentrated only on varying the span and depth of the box girder bridge. In the present study the effect of number of cells is considered In this paper work an attempt have been made to study the behavior of the pre-stressed multi-cell box girder bridges and a comparison is made between two cell, three cell and for cell girders of span 50 m. The analysis software used is CSi Bridge v18.2.0 and the loading considered was IRC class A loading as per IRC guidelines. After the completion of the analysis a comparative study is carried out with respect to Bending moment, Shear Force & Displacement variation of the of number of cell
