Some equivalent linearization techniques, applicable to problems dealing with non‐linear seismic amplification of layered soils, are systematically treated and critically compared in this paper. The discussion concerns, in particular, the theoretical consistency, the operative modalities, the computational complexity and the numerical reliability of these methods. A comparison is made between the results furnished by some techniques among those examined and the results obtained through a step‐by‐step integration of the non‐linear equations of motion, assuming as a test‐problem the one‐dimensional amplification of a horizontally stratified soil deposit characterized by the Ramberg‐Osgood constitutive model.
