摘要：

It is useful to reuse existing piles when the building is rebuilt, but the piles can be damaged by earthquakes. This paper describes the evaluation method of the lateral resistance of damaged piles. The major findings are summarized as follows: 1) It is important for evaluating the lateral resistance to consider the decrease in elastic modulus of pile and the formation of hinge region caused by the pile damage. 2) When the location of damage is below 2.1/?, the lateral resistance of the damaged pile is roughly equivalent to that of the fine pile despite the extent of damage.
