About Us
The Cold-Formed Steel Research Consortium (CFSRC) is defined by its mission, vision, and core values.
Mission: To provide world-leading research that enables structural engineers and manufacturers to realize the full potential of structures utilizing cold-formed steel. To provide the world’s pre-eminent training experience for cold-formed steel researchers. To provide the cold-formed steel industry with world-leading research capabilities that are responsive to both short and long term needs of the industry. To enable engineers to quickly utilize the latest research and speed adoption of research into appropriate codes and standards. To leverage existing industry funding to win external research funds.
Vision: The Consortium is recognized by engineers, manufacturers, students, researchers, and funding agencies as the premier organization in the world for performing research in cold-formed steel structures. The Consortium grows the cold-formed steel research enterprise in the United States to greater than one million dollars per year.
Values: General solutions using fundamental knowledge create the most long-term benefits. Enable the best engineers to solve the most unique problems. Use experiments to gain knowledge, not to fill tables.
Based on these principles a Charter for the CFSRC was established at the Johns Hopkins University in May 2013

Steel Deck Diaphragm Test Database V1.0
(2017-07)From the 1950’s to the present, a substantial number of large-scale tests have been conducted on steel deck diaphragms or concrete on metal deck diaphragms. The data, papers and reports for these tests are located in ... -
Characterizing the load-deformation behavior of steel deck diaphragms using past test data
(2017-06)Recent research has identified that current code level seismic demands used for diaphragm design are considerably lower than demands in real structures during a seismic event. However, historical data has shown that steel ... -
In-plane shear stiffness of bare steel deck through shell finite element models
(2017-06)The objective of this report is to explore the in-plane elastic shear stiffness of bare steel deck diaphragms through high fidelity shell finite element modeling. Profiled steel panels, i.e, metal deck, often serve as a ... -
Direct Strength Prediction of Cold-Formed Steel Beam-Columns
(2016)The Direct Strength Method (DSM) of cold-formed steel member design employs local, distortional, and global cross-section elastic buckling analysis with empirically derived “direct” expressions to predict member strength. ... -
Simulation of cold-formed steel structures
