Modeling the resilience of aging concrete bridge columns subjected to corrosion and extreme climate events

The aging and deterioration of highway bridges requires the development and implementation of technologies that provide enhanced resilience in short period of time. Fiber-reinforced polymers can be used as an effective resilience enhancement strategy for critical bridge components that provide rapid recovery of strength, ductility and minimize disruption of traffic. This paper introduces three measures of bridge resilience, namely load carrying capacity, ductility and rapid recovery of function, which can be used for the design and management of highway bridges.An example illustrates the modeling of the performance of corrosion-damaged reinforced concrete columns and how different rapid rehabilitation approaches can contribute to achieve resilient highway bridge structures.
