FRP-Strengthened RC Piles. I: Piles under Static Lateral Loads
Publication: Journal of Performance of Constructed Facilities
Volume 31, Issue 3
Abstract
Piles could be damaged under major lateral loading environment for a long period. The sources of lateral loads are lateral earth pressure, wind loads, seismic loads, impact loads from ships (berthing and mooring) eccentric loads on columns, river current and mud movement loads in alluvial settings (foundations subject to scour), ocean wave forces, slope movements, and cable forces on transmission towers. Hence, it is important to improve the lateral load capacity of pile foundation. In recent years, fiber-reinforced polymer (FRP) jacketing has become popular to retrofit existing deficient piles. The light weight, high strength, and corrosion resistance of FRPs made them particularly suitable for repair. This paper presents the experimental study on glass and carbon fiber-reinforced polymers (GFRP and CFRP) strengthened reinforced concrete (RC) piles subjected to static lateral loads. The effects of GFRP and CFRP strengthening on RC piles were investigated.
