Two discussions of the paper are presented. In the first, it is pointed out that since tangent modulus is used in nonlinear solutions, it is important to make certain that changes in such values associated with any approximation or correction, or both, of secant modulus are tolerable. It is noted that a 1967 paper presented a class of models for the yielding behavior of material and proposed both a parallel series model and a series-parallel model. The discussers also note-that all lumped-mass methods of nonlinear response calculations known to them generate high frequency oscillations in the acceleration time histories. In the second discussion, the discussers suggest a new rational approach to account for sample disturbance. The method is based on the normalized stress-strain behavior of soils.
