Nonlinear Response of Cohesive Soils under Thermo-Controlled Cyclic Torsional Loading
Shear modulus and damping ratio are considered essential soil parameters for ground response analyses under dynamic loading. The dependency of these two key parameters on the amplitude of induced strain for several types of soil has been studied in the laboratory and in situ tests under a limited set of controlled environmental factors, mainly soil confinement, plasticity, and moisture content. The present research investigates the influence of an additional potential critical factor, i.e., soil temperature. The thermo-controlled resonant column (RC) tests were conducted on low plastic clays (CL), and the effects of rising temperature on the soils’ dynamic parameters were thoroughly investigated, with particular emphasis on the shear moduli degradation and variations in damping ratios (D) vs. G/Gmax under thermally controlled conditions. The results suggest that the ground temperature might not play a significant role in the assessment of suitable values of the shear modulus and damping ratio for ground response analyses.
