Abstract

We discuss a paper dealing with the effect of surface wave solution non-uniqueness on 1D seismic site response analysis. We address some issues on the numerical simulations of seismic site response, specifically the correct definition of input motion. If a consistent framework is adopted, the solution non-uniqueness has negligible effect in amplification and acceleration response spectra for the presented dataset, confirming previous studies on the same topic.
