Article Preview

A NDT test, spectral analysis of surface wave (SASW) method, is a relatively new technique for examining the structural integrity of structural members of building structures. The SASW method has advantages among NDT methods that it needs an access from only one side of a testing object and can measure the dispersive characteristics in layered structures. This study is to model the wave propagation of stress waves in concrete media using a finite element method. Experiments using the NDT are to be conducted to investigate the wave behavior in concrete media. This study also evaluates the surface wave velocity of single layer cement mortar systems using an experimental analysis of the SASW method, and examines the corresponding results with numerical results. Specimen models were single-layer cement mortar slab systems.
