A Method for Estimating Static Elastic Pile-Head Spring Using the Impulse Response Excited by Human Power

Abstract

Recently, there are few construction works in vacant lot. Many construction works take place after demolishing the existing building. In such case, reuse of the existing piles is reasonable. We need a way to verify the performance of the existing piles for reuse. Therefore, in this paper, we proposed a simple method for estimating the static elastic pile-head spring using the impulse response excited by human power. We also proposed a simple method to simulate the impulse response of the pile-head.
