Abstract
|
|
|
|
| This paper presents a method to measure the viscous damping ratio of soils in isotropic stress conditions using a triaxial cell equipped with piezoceramic bender elements. The technique is based on the determination of a frequency response spectrum of the soil specimen by means of a continuous sine excitation generated by the emitter element. System identification procedures, known from modal testing, are applied for the interpretation of the spectra. Analytical expressions are found and a finite element model is developed to encircle the region of the resonant frequency. The test is performed on a reconstituted and undisturbed silt sample. |
