Experimental study of the bond interaction between CFRP and concrete under blast loading

Specific to blast loading, bond shear tests between carbon fiber reinforced polymer (CFRP) strips and concrete have not yet been reported in literature, the best knowledge of authors. Given high potential strengthening with CFRP increase resistance, it is necessary better understand dynamic interaction under impulse. This article presents a new experimental setup developed order study driven concrete. An evaluation at interface strip conducted identify parameters that affect strength loading. Several retrofitted specimens different are tested. explosive shock tube (EDST) set-up used generate Piezo resistive strain gauges digital image correlation (DIC) measurement record debonding process evolution along bonded area. As such, behaviour studied for three lengths effect wave within highlighted. The demonstrate occurs due combined effect: stresses caused by induced force additional resulting from propagation stress
