Bridge is a key element in any transportation system
which provides easy access over physical obstacles like road,
valley, water bodies etc. without closing the way underneath.
Among various types, use of box girder type bridges are gaining
popularity in bridge engineering because of its better stability,
serviceability, economy, aesthetics, structural efficiency and
rigidity in torsion. In this study, a box girder is analyzed by
changing its web inclination angle to the horizontal (90°, 83°, 76°,
69°, 62°) using finite element based software CSi Bridge. Finite
element models are developed keeping material properties, span
length, boundary conditions as constant parameters. All these
models are analyzed for self-weight, including load of wearing
coat and crash barrier, and live loads specified by Indian Road
Congress (IRC) namely IRC Class 70R and IRC Class-A loading.
Responses in terms of torsional moment, longitudinal moment,
support reactions, displacement and stresses are determined.
