Quick Assessment of the Anomalies in Concrete Structure Using Dispersive Characteristic of Surface wave
A waveform generated by a small impact hammer and recorded by single transducer is used to assess different kinds of anomalies in concrete. Using Short-Time Fourier Transform and the reassignment technique, the group slowness spectrogram can be calculated from the waveform. The surface wave response...
