Evaluation of Lateral Resistance of Damaged Pile Based on Full Scale Lateral Load Test


Abstract eng:
Existing piles can be used when a building is being rebuilt as these piles can reduce construction costs and wastes. Prior to their reuse, the appropriateness of the existing piles is inspected for reuse. In general, only piles judged to be fine are reused. Reusing damaged piles as well as fine piles can be useful for designing. This paper describes a method for evaluating the lateral resistance of damaged piles. The major findings obtained are summarized as follows: i) It is important to evaluate the lateral resistance of the damaged pile so as to consider the decrease in the elastic modulus of the pile and the hinge action of the flexural yielding part of the pile. ii) When the elastic modulus of the damaged part of the pile is about half of that of the fine part, the pile damage has little effect on the lateral resistance of the pile despite the location of the damage. iii) When the location of the damage is below 2.1/β, the lateral resistance of the damaged pile is roughly equivalent to that of the fine pile despite the extent of the damage.
