The behavior of normally consolidated saturated clays under cyclic shear stresses was studied. The study investigated he effects of cyclic shear stress amplitude, frequency, number of cycles and the change in the soil structure due to remolding on cyclic behavior of clays. An empirical procedure to evaluate the cyclic response of normally consolidated clay samples was developed. The samples were prepared in the laboratory using kaolinitic clay. The first group was obtained by consolidating kaolinitic slurry in large diameter odometers under axial stresses. The second group of samples was prepared by completely remolding 1-dimensionally consolidated clay blocks and by reconsolidating them under isotropic stresses. All tests were conducted under undrained conditions using a cyclic simple shear testing system. The results indicate a reduction in the shear strength under cyclic shear stresses. Estimations of the cyclic yield strength and other behavior patterns are discussed.
