Advancing Earthquake Engineering for Cold-Formed Steel Framed Buildings

This talk will summarize a multi-year NSF and industry cooperative effort to advance our understanding in the seismic behavior of, and improve the design of, buildings framed from cold-formed steel, known as the CFS-NEES project. Major activities in the CFS-NEES effort include: experimental shear wall testing, characterization, and modeling; experimental cyclic member testing, characterization, modeling, and design; and, complete building design, modeling, and shake table testing. The research enables performance-based design by providing the necessary building blocks for developing nonlinear time history models of buildings framed from cold-formed steel. In addition, the full-scale experiments demonstrate the large difference between idealized engineering models of the seismic lateral force resisting system and the superior performance of the full building system. Significant work remains to bring the findings to design practice, and this effort is both ongoing and an area of future need.

Benjamin W. Schafer is a Professor in the Department of Civil Engineering at Johns Hopkins University. He is also active in engineering consulting and is currently Vice President of NBM Technologies. He received his Ph.D. from Cornell University in Structural Engineering and his B.S.E. with Honors and Distinction from the University of Iowa. Prior to joining Johns Hopkins he worked as a Senior Engineer at Simpson Gumpertz & Heger Inc. Professor Schafer is the Director of the Cold-Formed Steel Research Consortium and North American Editor of the journal Thin-walled Structures. He serves on the AISI and AISC specification committees which create the nation’s standards for cold-formed and hot-rolled steel structures, respectively. He has previously served as Chair of the Department of Civil Engineering at Johns Hopkins, Chair of the Structural Stability Research Council, and President of the Cold-Formed Steel Engineers Institute. He is an award winning teacher and avid proponent of the tenets of Structural Art, which he teaches about in his course Perspectives on the Evolution of Structures. He is an avid runner and youth soccer coach and currently resides in Washington, D.C. with his wife and one child.
