numerical procedure for the analysis on web of composite beam by applying
stiffness on web for strengthening is herein studied. The study accounts
for nonlinear behaviour of materials used in steel concrete composite beam
including three dimensional material components of steel and concrete. In
particular, the mechanism of stress strain transition in material components
due to the openings on the web, applying stiffness on the web and applying
loads on combined vertical and horizontal directions are taken into account for
the analysis. The accuracy and reliability of the developed numerical model for
steel concrete composite beam subjected to combined hogging moment and
axial tension were ensured within 15% of deviation in predicting applied vertical
and axial loads including similar failure criteria by the existing experimental
program. Then, the developed model was included with web openings and
stiffnesses and the analytical results were compared with corresponding beam
without openings. The reported results demonstrated that, applying stiffness is
a valid tool for postponing the failure criteria while web buckling is postponed
or eliminated. The numerical procedure developed in this research allowed to
predict the actual nonlinear behaviour of the steel beam and the shear transfer in
the steel beam where the openings and stiffeners are located allowed to predict
the local behaviour of the composite beam including failure criteria and ultimate
strength of the steel concrete composite beam
