Abstract:
The poor performance of conventional chip and patch methods for repairing corrosion damaged piles has led to renewed interest in the use of fiber reinforced polymers (FRP). Over the past decade, laboratory research complemented by numerous field demonstration projects has led to improvements in the design, construction and monitoring of FRP pile repair. The two principal areas of advancement were in the development of techniques borrowed from the composites industry for improving FRP-concrete bond and in the incorporation of a sacrificial anode cathodic protection system within a FRP wrap. Both developments enhance the competitiveness of FRP pile repair. This paper provides an overview of laboratory and field demonstration studies in recent years that led to these advancements.
