Abstract

Synopsis: A method for strengthening reinforced concrete members using mechanically-fastened FRP (MF-FRP) has been studied in laboratory investigations and in several bridge strengthening demonstration projects. The strengthening is obtained by attaching FRP strips, with high bearing and longitudinal strengths, to concrete elements using steel power actuated fastening "pins" (PAFs), steel anchor bolts or concrete screws, or a combination thereof. The MF-FRP method requires minimal surface preparation and permits immediate use of the strengthened structure. Published research on this method with a range of member sizes has shown promising results in terms of installation efficiency, level of strengthening achieved, and preventing strip delamination before concrete crushing. This State-of-the-Art paper presents an overview of work conducted over the last 10 years on experimental aspects of the MF-FRP method, with beams as well as one-way and two-way slabs. A database of collected test results for MF-FRP strengthened beams and one-way slabs is presented.
