An experimental study on the integrated health monitoring of cast-in-situ concrete pile foundations is presented using vibration and wave measurements. The health monitoring strategy is a two-stage damage detection scheme before and after excavation as in the case of the previous paper. A series of cyclic loading tests on cantilever-type specimens of cast-in-situ concrete pile have been performed to simulate the development of seismic damage. Four damage detection tests, i.e., vibration generator, impact hammer, acoustic emission and ultrasonic wave tests have been carried out during and after successive loading cycles. Based on the experimental results, the usefulness and limitations of the proposed damage detection scheme are discussed for cast-in-situ concrete pile foundations.
