Structural Damage Detection Based on the Wave Velocity Analysis

Abstract:

The wave velocity analysis is a kind of popular geophysical method. These years it is also used in structural damage identification which is discussed in this paper. This method is used to detect the interior damage of structure and is verified to recognize the damage effectively. The expression of the vertical and horizontal velocity is deduced and the wave velocity function curve is drawn according to velocity variety rule. The two dimensional and three dimensional wave field figure is drawn according to the wave velocity analysis and it shows the distinguish between the damaged and integrated structure. We can see the change of the wave shape and velocity and we can identify the damage in terms of the velocity variety rule. So the method introduced in this paper is verified to be a pontential way to identify the structural damage.
