AB  - Use of castellated steel beams for different structural purposes now a days is widespread. The
principal useful of castellated steel beams is to enhanced strength due to increasing depth of beam section
without any increasing in weight. In this study, steel IPE200 standard section was used to fabricate six
specimens with expanded castellated section with and without strengthening by high strength concrete and
laced reinforcement within the two side of their webs. Experimental test was achieved to investigate failure load
and mid-span section by applying two-point load on beam surface having simple support condition. The
experimental results show that the load carrying capacity and the deflection values at ultimate load in
the mid-span section were increased for all strengthened beams compared with reference beam. Abaqus 6.14
Software was used to carry out the numerical modeling for tested beams. It was noted that there is good
agreement between numerical and experimental results.
