05.01.18 At the 2018 NASCC Steel Conference in Baltimore, LeMessurier President Peter Cheever moderated two sessions on “Research on Low-Ductility Concentrically Braced Frames.” Larry Fahnestock of the University of Illinois Urbana-Champaign (UIUC) and Eric Hines of LeMessurier and Tufts University served as panelists for these sessions, sharing the results of 15 years of collaborative work between LeMessurier, Tufts, UIUC, and the Ecole Polytechnique in Montreal on design for moderate seismic regions. LeMessurier has published over two dozen articles on this subject since 2003, and has worked with the UIUC and Montreal team to execute over $1.2 M in funded research on this subject, establishing our office as the leader in seismic design for steel buildings in moderate seismic regions. The rational design philosophy that has evolved during this work has elevated the national discourse on structural behavior in moderate seismic regions and has the potential to make significant impacts on the way that engineers east of the Rockies approach seismic design.
