his paper describes the strengthening of composite beam by providing

openings on web of composite beam subjected to hogging moment and

axial tension. A nonlinear three-dimensional numerical model was developed

for steel concrete composite beam subjected to combined hogging moment and

axial tension and the predicted applied vertical and axial loads were found within

15% of deviation including similar failure criteria. Failure of the bond between

studs and surrounding concrete was observed due to the extensive axial loads

and flexural stiffness of studs became smaller as the increase of axial loads.

Web openings were applied subsequently and it was found that web openings

have influenced the failure criteria and ultimate strength of the composite

beam. In addition, a parametric study, by applying stiffness on the web of the

composite beam including the various parameter of stiffness, was then carried

out in the developed numerical model. As a result, applying stiffness on the

web of the composite beam generally gives much better ultimate strength,

including postponing first failure mode, which presented herein as conclusive

of strengthening method
