Abstract: The Spectral Analysis of Surface Waves (SASW) method is a nondestructive testing procedure which has been extensively used to determine in situ the elastic moduli of soils and pavements (for low levels of strain) and their variation with depth. In the work described in this paper, the applicability of the SASW method to assess the quality of concrete in the members of a structure and to identify cracks in concrete members was investigated. The results of a number of analytical and experimental studies on small scale beams are presented.
