Professor seeks to improve steel structures via geometrical cutouts

Blacksburg, Va. While working as a structural engineer in California, Matthew Eatherton saw myriad ways the steel industry could break from century-old methods and delve into the then-burgeoning fields of subtractive and additive manufacturing the later commonly referred to as 3D printing and improve building performance. Now an assistant professor with Virginia Techs Charles E. Via Jr. Department of Civil and Environmental Engineering, Eatherton will be using a five-year, $500,000 National Science Foundation CAREER Award to research how steel plates with carefully designed geometric patterns or voids cut into them can better withstand everyday loads and extreme events high winds, blast or shock from an earthquake than the standard solid steel plates currently used.
