Ensuring the full connection between steel sheet and concrete after applying a load to composite slabs is still nowadays something difficult to achieve. The aim of the current project is to reveal the experimental results of a new bonding system, under patent  by the Universitat Politècnica de Catalunya (UPC) which its function is to resist the shearing forces and separating forces generated between both materials when the composite steel-concrete element is loaded ensuring the commented full connection between materials and working as a composite cross section. The new method has been validated with amount of tests which results have been compared with different commercial carbon steel sheeting slabs and ferritic stainless steel sheeting slabs, all of them with traditional embossment as a connection system. These tests have been carried out in “Laboratori d’estructures i resistència de materials” (LERMA). The comparison between composite slabs using traditional embossments and those which use new connection system is extremely deep. The ultimate state values of new composite slabs were reached with inexistent slippage, so the ultimate bending moment resistance is higher on new composite slabs. Moreover, theoretical predicted calculations, always by the Eurocode4directions, have been done trying to predict the ultimate state service for each studied composite slab. Then it has been compared such predicted results with the experimental testing. Comparison of experimental and analytical results of the load-carrying capacity of composite slabs revealed that agreements between these values are sufficiently good.
