The use of concrete in combination with steel in structures can play an important role in improving the structural behavior, ie increase in strength and formability. In many cases, in steel structures that do not meet the considerably shaping criteria.In this study,a solid concrete beam and steady steel beams were modeled using ABAQUS finite element software and verified by a laboratory model. In the following six groups, the difference in specimens was only in the manner of connecting concrete to steel, and for each of the six series, five different thicknesses were considered and investigated,which resulted in the following conclusions. Increasing the number of cutters increases the resistance of composite beams.By increasing the number of simple cut-offs into two rows, 10% of the final bending strength of the composite beams increases.The difference between the studs and the corners is not significantly different.The effect of simple cut-offs and L shapes has been around 2%.
