Abstract

The laid piles under the ground are damaged in an earthquake. Since it is difficult to install a sensor at a pile, we cannot detect whether the piles are cracked or not. The pile is excited by the elastic wave from the ground surface and then bending deformation of it is occurred. Therefore, installing an angular velocity sensor on top of the pile, we can detect whether the pile is cracked or not by measuring the angular velocity of it. In this study, the experiment in the air and the simulation is conducted as a basic study. From these results, it is clear that the difference of bending strain is applicable to the damage detection of the laid piles.
