ABSTRACT: Compacted gravel is often used as engineered fill to provide the needed bearing capacity for structures. The dynamic properties of the gravel fill, such as nonlinear shear modulus, are required in seismic analyses to evaluate the response to dynamic loading. From a series of Resonant Column and Torsional Shear (RCTS) tests on two ...
