BLAST-PROOFING OF UNREINFORCED MASONRY (URM) WALLS WITH GFRP
Abstract eng: An experimental program sponsored by the Technical Support Working Group (TSWG) and conducted by the Defense Threat Reduction Agency demonstrated significant increases in load carrying capacity of unreinforced masonry (URM) walls retrofitted with various combinations of Glass Fiber Reinforced Polymer (GFRP) and GFRP/shotcrete. Four walls (two eleven feet wide by twelve feet high, and two 18 feet wide by 12 feet high) were constructed of 6"x16"x8" hollow concrete masonry units and reinforced with E-glass fabric on the exterior and in two cases reinforced with 2" of 4000 psi shotcrete on the interior. The room was subject to an internal blast from a 2 lbs. TNT equivalent charge that generated pressures as high as 72 psi and 0.08 seconds in duration. This paper discusses the performance of the retrofitted walls.
