SOUTH CAROLINA — New research at Clemson University is aimed at helping expand the use of mass timber, an environmentally sustainable option for the construction of new buildings. A research team that brings together civil and environmental engineers, architects and foresters will work over the next three years to develop an all-timber structural floor system for buildings. …The project is funded with $1.1 million from the U.S. Department of Energy Advanced Research Projects Agency-Energy. The principal investigator is Brandon Ross, Associate Professor of Civil Engineering at Clemson. “What’s new here is we are coming up with a system that can span much farther” Ross said. …The floor system that researchers have in mind would utilize outer layers of cross-laminated timber with glued-laminated timber beams in-between, forming a box-like structure. It would include interior space for electrical conduits, plumbing and mechanical ducts.
