Abstract

Advanced composite materials, predominantly developed for use in the aerospace industry, have shown a great potential for strengthening, retrofitting and repair of existing buildings and bridge structures to extend their service life well into the 21st century. With the broader availability of glass, aramid and carbon fibers, as well as automation in the manufacturing process, PMCs (Polymer Matrix Composites) can be affordable and competitive with conventional structural rehabilitation materials and processes. The structural effectiveness of PMCs in rehabilitating existing structural systems has repeatedly been demonstrated with full or large-scale structural tests at the University of California, San Diego. Bridge columns were seismically retrofitted and repaired with fiberglass, carbon and hybrid composite jackets and composite retrofits were shown to be just as effective as conventional steel jacket column retrofit technology to enhance column shear strength and ductility. Repair and strengthening measures using PMCs were developed for, among others, slabs, bridge decks, and water pipelines. The paper will provide a general overview of the use of advanced composites in the rehabilitation of existing structural systems, documented by large and full-scale laboratory tests. Field applications as well as future design and research developments with advanced composites for civil applications are presented.
