Composite steel assemblies are an efficient and popular structural option for floor construction. Figure 1 shows a typical assembly, consisting of a steel beam, metal deck, concrete slab, and shear connectors.
Since the development of the first specifications for cold-formed steel (CFS) building construction in 1946, the American Iron and Steel Institute (AISI) has been working to develop design standards to improve performance and accessibility for designers and structural engineers.
Curtain walls are often the focal point of aesthetic design for a multi-story building. Behind the attractive façade are the pedestrian, yet arguably more important, functional components that ensure safety and reliability—fasteners that transfer loads both imposed and experienced by the assembly to the building’s structural framework.
Some of the most attention-getting projects these days involve architectural coiled-wire fabric—a more affordable alternative to traditional woven mesh that delivers equal or superior aesthetics, as well as functionality and performance.
Architectural and engineering firms are increasingly exploring stainless steel’s possibilities as a structural material as new research, structural codes, and design guides become available. Most designs have used the familiar Types 304L or 316L alloys from the austenitic family of stainless steels.
