Pre-panelized assemblies, while different from modular, can provide multiple benefits such as truncated construction time, increased safety, ease of quality control, and reduction of jobsite waste. Both structural steel and cold-formed steel (CFS) elements in these panels provide straight, dimensionally stable substrates for a variety of finishes and construction techniques.
The American Iron and Steel Institute (AISI) has published a new cold-formed steel research report on loadbearing clip angle design. The report “RP18-4: Load Bearing Clip Angle Design – Phase II” presents the second phase of a research project aimed at developing design methods for three limit states of cold-formed steel clip angles—shear, compression, and pullover of the screw connections.
The American Iron and Steel Institute (AISI) has published a new research report on the recalibration of the load and resistance factor design (LRFD) and the limit states design (LSD) resistance factors for cold-formed steel compression members when the strength is predicted using the direct strength method.
In response to President Donald Trump’s announcement last month that the United States would be imposing tariffs on metal imports from Canada, the European Union, and Mexico, the Canadian government introduced dollar-for-dollar retaliation duties. Beginning July 1, a number of U.S. steel products faced fees of 25 percent, while an array of aluminum products cost Canadian importers 10 percent more.
Five research proposals deemed impactful for the reliability, performance, and cost-competitiveness of cold-formed steel framing products have been selected by the American Iron and Steel Institute Standards Council for its 2018 Small Project Fellowship Program.
