• Abstract:
  This report presents the use of externally bonded fiber reinforced polymers (FRP) laminates for the flexural strengthening of a ; concrete bridge. The bridge selected for this project is a two-span simply supported reinforced concrete slab with no transverse ; steel reinforcement located in Phelps County, MO. The original construction combined with the presence of very rigid parape ; caused the formation of a 1-inch wide longitudinal crack, which resulted in the slab to behave as two separate elements. The ; structural behavior was verified using a finite element model (FEM) of the bridge. The bridge analysis was performed for ; maximum loads determined in accordance with AASHTO 4th edition. The strengthening scheme was designed in compliance ; with the ACI 440.2R-08 design guide for externally bonded FRP materials, to avoid further cracking and such that the transverse ; flexural capacity be higher than the cracking moment. The FRP strengthening technique was rapidly implemented. After the ; strengthening, a load test was performed to validate the bridge model and evaluate the structural behavior according to the AASHTO specificatiions. The bridge deck was retrofitted after the longitudinal crack was injected with epoxy to allow continuity in the cross section.
