The increasing uses of FRP materials for the strengthening and upgrade of buildings has motivated the international engineering community to produce guidelines for the proper design, handling and installation of the externally bonded FRP systems. Thus, independent efforts coordinated by different organizations such as the Japan Building Disaster Prevention Association (JBDPA) and the American Concrete Institute (ACI) have led to implementing appropriate provisions. the JBDPA guidelines mainly focus on seismic retrofitting of structural elements, which implies the strengthening for shear of deficient structural elements. This paper describes and comments on some of the design approaches provided by the JBDPA guidelines for the strengthening of reinforced concrete (RC) columns. This was one of the main targets of the Japanese experience on infrastructure strengthening, which became an imperative task after the post-earthquake observations of the damage caused by the Kobe earthquake in 1995. Finally, comparisons with the ACI guidelines for the strengthening of RC members with FRP systems are also formulated. © 2004 ASCE.
