The scope of this experimental and numerical works is to investigate and study the effect of concrete compressive strength on flexural behavior of composite vierendeel steel-conncrete composite beams when considering the top chord member of the truss (compressive elements) is the concrete slab. The works consist of manufacturing and testing three specimens of 2000 mm span with slab width 1000 mm and each specimen contains two truss. The control beam has 25 MPa compressive strength and other beams have (35, 50) MPa. The results that attained from this study are load-deflection curves, ultimate load capacities, strains, crack patterns and failure modes. The concludes from this study are; an increase concrete strength (f’c) of slab from 25 MPa to 35 MPa leads to increase ultimate load capacity by (28.89) %. Whereas increasing concrete strength from 25 MPa to 50 MPa leads to increase ultimate load capacity by (91.63) %.
