This research concerns the development of guidelines

for the design and use of externally-bonded FRP

strengthening systems on bridges in Michigan. Si

x representative international FRP-related guidelines

were analyzed and compared for applicability and

effectiveness to MDOT needs. An experimental

program involving natural and accelerated laboratory

weathering was conducted to determine acceleration

factors appropriate for the climate of Michigan.

Bond pull-off and other specimen tests were used to

establish rates of strength degradation, and an envi

ronmental reduction factor was estimated from these

results. From the review of the existing guidelines

as well as the test results, recommendations for design

as well as installation, quality contro

l, inspection, maintenance and repa

ir were proposed that are based on

modifications to as well as a synthesis of existing provisions
