Experimental study on impact resistance effect of two kinds of NSM FRP rods on RC beams

Abstract

In order to investigate an impact resistant effect of two kinds of Near-Surface Mounted (NSM) Fiber Reinforced Polymer (FRP) rods for RC beams, static three-point loading test and falling-weight impact loading tests for the RC beams were carried out. Here, Aramid FRP (AFRP) and Carbon FRP (CFRP) materials were considered. The results obtained from these experiments were as follows: 1) the RC beams strengthened with both FRP rods statically reached an ultimate state due to FRP rods being debonded; 2) impact resistant effect of AFRP rod will be higher than that of CFRP rod; and 3) impact design formula for normal RC beams may be applicable for strengthening design for the RC beams with NSM-FRP rods.
