Abstract

An experimental study was carried out to evaluate the structural performance of new retrofitting technology using high performance carbon fiber bar and strengthening metal fittings. Experimental programs were accomplished to evaluate the structural performance of test specimens, such as load-displacement relationship, crack propagation, ductility, and strain of retrofitting materials etc.. Specimens(BCR2, BCR2-AF1) designed with the new retrofitting technology using high-performance carbon fiber bar and strengthening metal fittings showed much higher load-carrying capacity and ductility compared to specimens(BC1P, BC2P, BS30) designed with the conventional retrofitting method.
