Fiber Reinforced Polymer Composites for Infrastructure Strengthening - From Research to Practice

Abstract

This paper focuses on the use of emerging technologies for the upgrade of the transportation infrastructure. A number of bridge rehabilitation projects conducted in the State of Missouri in the last three years were selected for presentation. The review is limited to bridge superstructure strengthening to correct flexure and shear deficiencies in non-seismic applications. Strengthening of concrete members with externally bonded fiber reinforced polymer (FRP) laminates or near surface mounted (NSM) bars has received remarkable attention. The design and construction principles for use in practice have been finalized by the American Concrete Institute (ACI). On the application side, FRP materials have been used in some multi-million dollar projects for strengthening bridges, parking garages, multi-purpose convention centers, office buildings and silos. The drivers for this technology are several, but perhaps the most relevant ones are the ease and speed of installation. In the repair/upgrade arena, one of the most important unresolved questions remains that of durability. Addressing this issue will increase the degree of confidence in the technology and allow for its full exploitation.
