Behavior of residual soil with high silt content under low frequency cyclic loading using modified direct simple shear apparatus

This paper presents the experimental work on typical Malaysian silty residual soils in order to evaluate fundamental soil properties in particular its stiffness under low frequency cyclic loading. There has been very little information on local silty residual soils which is very important for loca...
