Verification calculations of the interaction between the structure and the soil under seismic excitation have been carried out using the effective seismic input method implemented in LS-DYNA software, Hallquist (2017). Two test examples performed using the ASC SASSI software, Ghiocel (2016), were used as control solutions.

Verification of the effective seismic input method implemented in the LS-DYNA software resulted in good agreement with results obtained using the control solutions. In the case of surface placed structure, the maximum error in response spectra calculation is less than 10 %. For the embedded structure, less accurate but more conservative results were obtained, with the maximum error of 24.5 % in the calculation of ZPA.
