Based on the solution to the dynamic impedance functions of pile-soil foundations under the conditions of layered soil

it studies the earthquake response of stadium stands with pile-soil structure interaction by combining the constant impedance method with the substructure method via finite element time-history analysis. The finite element calculation results show that the maximum displacement and maximum acceleration response of the stadium stands under the action of different seismic waves are different due to the differences in the frequency spectrum characteristics of the seismic waves. The maximum displacement and maximum acceleration response of the stadium stands under the action of EL-Centro wave and artificial wave are close; the response under the action of TAR_TARZANA wave is slightly smaller

compared with the results of EL-Centro wave and artificial wave. Moreover

under the action of the three seismic waves mentioned above

the seismic response of the upper stand is obviously larger than that of the lower stand.
