     steel-concrete-steel beam or as known in other engineering phrases (sandwich beam) is part of the modern structural frames which assist the interactions between concrete and steel, knowing that this parts of structure looks similar to the sandwich slab. the sandwich beam can be created by replacing the main longitudinal steel bars for the tension and compression with an equivalent one of steel plates and binding both the top and bottom plates using stud connectors that replace strips on the standard reinforced concrete beam and filling all the spaces between the two plates with concrete. also all of the practical results were compared to the numerical results using finite element methods techniques by software computer engineering program (ansys ver.11) and it has been noticed that all of the practical results are close together with the numerical ones; also it has been noticed that the bearing force of the sandwich beam is more powerful, durable and reliable from the standard reinforced concrete beam and that’s mainly because of the full and strong correlation between the beam components.
