Welcome to the CFS-NEES web page. CFS-NEES is the shortened name for the NSF project: NEESR-CR: Enabling Performance-Based Seismic Design of Multi-Story Cold-Formed Steel Structures. Lightweight cold-formed steel (CFS) framing is a unique and effective building solution for low and mid-rise structures, but one in which much remains to be understood for the system to achive its full efficiency and for modern performance-based seismic design methods to be fully enabled. The goal of this research is to generate the knowledge needed to increase the seismic safety of buildings that use lightweight CFS for the primary beams and columns, and enable engineers to account for complete building performance in predicting the response of these buildings to earthquakes.
This award is an outcome of the National Science Foundation (NSF) 09-524 program solicitation "George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) Research (NEESR)" competition and includes Johns Hopkins University (JHU) (lead institution) and Bucknell University (subaward). This project used the NEES equipment site at the University at Buffalo (UB), State University of New York. Link to the NSF announcement. The research is also being performed in collaboration with the American Iron and Steel Institute and additional sponsors. Major testing was completed in 2013 and the project is anticipated for final closeout in Fall 2014. Additional information is available from the NEES hub.
