Abstract:

Corrosion of RC bridge element is one of the major deterioration distresses in US Highway Bridges. FRP composites jackets can be

the economic and effective corrosion repair in 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 test, the externally bonded FRP composites

shown to have corrosion control properties in chloride laden environment.

In the 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 composites jackets are considered as a

corrosion repair material for corroded RC bridge pier column and a life-cycle cost analysis procedure is proposed based on the

probabilistic model. The use of this probabilistic model needs corrosion parameters, FRP composites 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.
