Damping of geo-materials in resonant column test is commonly evaluated with two alternative experimental methods; during a steady-state vibration (SSV) and during free-vibration decay (FVD).
In the second part, the materials and experimental techniques of the study are described briefly and the background of determining material damping in a resonant column test is also presented along with the analytical formulae.
Introduction Stiffness (G) and damping (Ds) are important properties in order to capture the complete dynamic behavior of geo-materials.
Equipment, Materials and Methods A crushed rock of hard sub-angular to angular particles was tested in the study.
