h i g h l i g h t s New full-connection bonding technology between steel sheet and concrete for composite slabs is presented and compared with common embossments technology. Full-connection between steel and concrete is achieved with the new system until yielding of both materials, regardless of the material type: ferritic stainless or common galvanized steel and normal or lightweight aggregate concrete. Longitudinal shear failure mode is practically extinguished. The ultimate loads with the new bonding technology are significantly greater than those with common embossments. The slabs including the new technology has shown significant ductility provided by material yielding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
