Environmental, Mechanical and Life-Cycle Cost Analysis of Bridge Columns

Corrosion of reinforced concrete (RC) bridge elements is one of the major deterioration distresses in U.S. highway bridges. Fiber reinforced polymer (FRP) composite jackets can be the economic and effective corrosion repair method in the future, though its practices and field installation as a means of corrosion repair are limited due to limited durability studies. However, in many laboratory tests and some field tests, the externally bonded FRP composites have been shown to have corrosion control properties in a chloride laden environment. In this study, concrete encased in FRP jackets and steel-concrete-FRP columns were subjected to severe environmental cycles. The behavior of the conditioned cylinders was tested under axial cyclic loads. Moreover, the FRP composite jackets are considered as a corrosion repair material for corroded RC bridge pier columns and a life-cycle cost analysis procedure is proposed based on the probabilistic model. The use of this probabilistic model needs corrosion parameters, FRP composite durability properties as a statistically distributed random variable input in Monte-Carlo Simulation. The life-cycle cost includes the agency related cost of inspection, maintenance, repair, rehabilitation, cost of failure represented as probability of failure of repaired column, and users cost.
