Home defense: Testing new building materials against wind-blown debris

In tornadoes and hurricanes, materials used to build homes become missiles, destroying neighboring houses and taking lives. At Clemson University, engineers who specialize in structural reliability are testing new building materials to see how well they stand up to severe storms by shooting them with two-by-fours from an air cannon at 60, 80 and 100 miles-per-hour. Preliminary testing on one new material, cross-laminated timber (CLT), shows much greater protection than conventional building practices. CLT has been used in Europe for years, and is only recently finding a place in the U.S. market. Research by Clemson and others will help create building codes to ensure safe construction and safer buildings.
