Abstract

Twenty-eight fiber-grating sensors were used to instrument two reinforced concrete beams that were externally strengthened with composites on the historic Horsetail Falls Bridge in the Columbia River Gorge. Sensor assemblies were placed in the beams and mounted on the outside of the composite to provide performance data.
