Paper Abstract

A number of reports have been published on investigation of damage to pile foundation of buildings due to the 1995 Hyogoken-Nambu earthquake. The result of these investigations indicates the urgent need for development of techniques to enable quick and accurate assessment of damage to piles following major earthquakes. Authors have been conducting a series of researches on the development of monitoring techniques to detect damage to concrete piles due to the earthquakes. The sensor using carbon fiber has already been proposed, and its applicability has been investigated by various kinds of experiments on carbon fiber and the sensor. In this paper, performance of the sensor evaluated by experimental analysis is discussed in detail. Then, the examples of installation of the sensor to actual structures are described to show the applicability to practical purpose.
