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
