Resumen
The paper presents an iterative procedure for the time domain deconvolution in nonlinear
elastoplastic materials. The approach is intended for the generation of input motions for
dynamic soil-structure interaction (DSSI) numerical analyses when the desired earthquake
is specified at the surface of a nonlinear soil deposit. The main advantage is that the same
constitutive model (or models) to be used in the DSSI simulation, to characterise the soil
deposit, is also employed in the deconvolution procedure. Therefore, the desired surface
motion is recovered from the free-field propagation of the resulting input motion at the
base of the numerical model, accounting for the assumed constitutive behaviour of the
ground. An application example is also presented, where the potential of the proposed
approach is shown.
