Numerical method to determine soil stiffness by cyclic load

It is demonstrated that bed stiffnesses obtained by processing results of cyclic tests by the method of rapid Fourier transforms (WAK test) and numerical calculation, are rather approximate. Results of this investigation can be used for cyclic tests of a model in a centrifuge (during repeated loadin...

description It is demonstrated that bed stiffnesses obtained by processing results of cyclic tests by the method of rapid Fourier transforms (WAK test) and numerical calculation, are rather approximate. Results of this investigation can be used for cyclic tests of a model in a centrifuge (during repeated loadings) for comparison with the (static) stiffness of the soil as determined from WAK-test data.
