Abstract
The purpose of this abbreviated paper is to analyze the applicability of FRP (fiber-reinforced polymer)-strengthening systems
for retrofitting RC (reinforced-concrete) highway bridges to stabilize structural members under earthquake conditions. Three
earthquakes in California, with multiple bridge failures, drove the requirement to improve bridge design and methods of structurally
upgrading critical bridge components to withstand impacts of earth tremors. Retrofitting RC bridges by encasing and strengthening
bridge bents with FRP-systems provides an effective method of mitigating the impacts of earthquake loading. This analysis considers
types of retrofitting applications on bridge bents and the advantages of FRP systems to increase structural member axial capacity
and ductility in columns and beams.
