Abstract

Fiber reinforced composite materials are frequently used in the rehabilitation or upgrading of reinforced concrete structures. Within this context, current international guidelines have set rules for the design of FRP strengthening applications. Nevertheless, some specific topics for seismic applications have to be studied more deeply. One of these is represented by the FRP plating of members subject to bending moment, or bending moment and axial force, when such an intervention is executed close to beam-column joints, due to the need for suitable FRP anchorage devices. There are still only a few not conclusive studies currently available in literature on this topic. In this paper, the main features of a device prototype, proposed by the authors, and the results of an experimental program are reported. The tests have been performed at the Testing Laboratory of Material and Structures of the Department of Civil Engineering of the University of Salerno, within ReLUIS (University Network of Seismic Engineering Laboratories) Consortium research program.
