Repair of steel composite beams with carbon fiber-reinforced polymer plates
One significant cause of deterioration of steel bridge structures is the corrosion due to extensive use of deicing salts in winter weather. The investigation presented i this paper focused on the behaviour of steel composite beams damaged intentionally at their tension flange to simulate corrosion and then repaired with carbon fiber-reinforced polymer (CFRP) plates attached to their tension areas side. Damage to the beams was induced by removing part of the bottom flange, which was varied between no damage and loss of 75 % of the bottom flange. The following conclusions can be made: Section and member behaviors were accurately predicted using the proposed nonlinear analysis. Damage to the bottom flange degrades both the flexural stiffness as well as the strength of the beam. The elastic flexural stiffness of damaged beams can be partially restored (up to 50 %) with the use of CFRP plates for the system investigated. Strength of damaged beams can be fully restored to its original, undamaged state with the use of CFRP plates for the system investigated. Ductility is slightly reduced with the addition of CFRP plates. The bond between thesteel and CFRP is not a problem for the system investigated.
