international conferences.

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
