Comment on 'Effect of surface wave inversion non-uniqueness on 1D seismic ground response analysis' by Roy et al

摘要

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
