EQUIVALENT UNIFORM CYCLE CONCEPT FOR SOIL DYNAMICS
While additional studies of this nature would be appropriate, especially using direction independent tests such as cyclic simple shear, torsion shear, or shaking table, the writers feel justified in concluding that the data presented herein generally confirm the validity of the equivalent cycle or the cumulative damage method of dealing with irregular loading effects on soil. Some other aspects include a clarification of the relations between damage potential and equivalent number of uniform cycles, certain peculiarities of the cyclic triaxial test on saturated sands that may not be significant for clays, and a perspective comparison of the range of data scatter for cyclic tests on soil as compared with other materials. Thus, while the damage potential or equivalent cyclic concept may not be exactly valid for all cases, its continued use in the field of seismic stability analyses of soils seems to be a valid pragmatic approach. /Author/
