Abstract

In this paper, a non-destructive damage evaluation procedure is presented, which aims at detecting early or fatal cracks in existing piles after severe earthquakes. The bending motion of a target pile excited by an impulsive load, which is induced by hammering at the ground surface nearly, is measured at the top to obtain the dynamic compliance of the pile in one direction. Numerical simulations and experiments show that evaluating the dynamic compliance in every direction can suggest the severity of the cracks as well as their location and orientation.
