Many reinforced concrete (RC) solid slab bridges in Missouri and surrounding states were constructed in the first half of this century. These bridges were designed to accommodate traffic loads smaller than currently permitted and with no consideration to seismic vulnerability. At present, many of these structures have not deteriorated but are structurally deficient. Solutions for the upgrade of these bridges using economical and reliable techniques are of great interest. To this effect, advanced composite materials made of fiber reinforced polymers (FRP) have a great potential.
