Matt Eatherton has received two prestigious fellowships, including the Earthquake Engineering Research Foundation (EERI) Graduate Fellowship and the Diffenbaugh Fellowship from the University of Illinois at Urbana-Champaign. The EERI Graduate Fellowship is designed to foster the participation of capable individuals in working toward goals and activities of the National Earthquake Hazards Reduction Program. The Diffenbaugh Fellowship is awarded to graduate students who are or were residents of Missouri. Both fellowships are awarded on the basis of academic excellence and scholarly promise. Matt is a Ph.D. candidate working with Prof. Jerome Hajjar on the NEESR project entitled "Controlled Rocking of Steel-Framed Buildings with Replaceable Energy Dissipating Fuses" conducted in conjunction with researchers at Stanford University. Matt's research is focusing on developing a new seismic-resistant system consisting of three major components: 1) a stiff steel braced frame that remains virtually elastic, but is not tied down to the foundation and thus allowed to rock, 2) vertical post-tensioning strands that anchor the top of the frame down to the foundation, which brings the frame back to center, and 3) replaceable structural fuses that absorb seismic energy as the frames rock. Matt has completed eight large-scale experiments of the structural system in the MUST-SIM facility at the University of Illinois at Urbana-Champaign, including both quasi-static cyclic tests and hybrid simulations. He has also conducted extensive computational simulations of the response of this structural system. The final stage of the project involves conducting large-scale shake table tests of this system at the E-Defense testing facility in Miki Japan. He will complete his work by formulating seismic design provisions for this structural system.
