- Abstract:
- The Resonant Column (RC) test is the standard to determine dynamic and static parameter of soils and rocks under different shear strain and confining conditions. The test consists of vibrating a cylindrical specimen in torsion establishing a fundamental mode, measuring the resonant frequency and amplitude of vibration with a frequency search. In order to minimize the spectral content beyond the used frequency range, borrowing a radar technique, a “Chirp” is used. This continuous modulation improves the system measurement performances, minimizing the effect of the number of cycles, reducing the test time and increasing the frequency resolution.
