Tests have been conducted on both reconstituted and undisturbed fine grained hollow soil specimens with the plasticity index varied from 5 to 18. Stress controlled dynamic tests were performed under different cyclic shear stress ratios, and monotonic tests were conducted on soil specimens controlling the strain rate in order to determine the pre-cyclic and post-cyclic static shear strength. The post-cyclic monotonic shear strengths were evaluated after various numbers of cycles of dynamic loading. If soil undergoes a cyclic shear strain level below the cyclic yield strain, reduction of monotonic strength of reconstituted and undisturbed specimens is limited, but when cyclic shear strain level is larger than yield strain monotonic strength decreases down to 40% of its initial strength.
