The Behavior of Plugged Pipe Piles Strengthened with Biaxial Carbon-Fiber under the Effect of Lateral Loads

Abstract

This paper presents an experimental study to investigate the behavior of plugged pipe pile strengthened with biaxial carbon fiber under the effect of lateral loads in sand. The change of plug length and incremental filling ratio of pipe pile under static lateral load is considered. The model of piles is embedded in dense sand with different slenderness ratios of pile. In addition, different ratios of confining length of biaxial carbon fiber are used. The results indicated that the ultimate lateral resistance of plugged pipe pile increases with increase of the confining length of carbon fiber.
