| Abstract |
This study examines the behavior of the soil-basement system under seismic loading, focusing on the kinematic interaction effects using
two-dimensional finite element analysis. The analysis evaluates the accuracy of basement response prediction methods outlined in KDS 41 17
00, FEMA P-1050, and ASCE/SEI 7-22 standards. Results indicate that the ratio of response spectrum (RRS) at basement depth closely align
with FEMA standard, though significant amplification occurs in the short-period range at surface depth due to the inertial effects of stiff
basements. Additionally, the ratios of short-period and long-period site coefficients show a linear relationship with the acceleration and
displacement ratios. Long-period effective site coefficients (Fv,eff) accurately predict basement responses, while short-period effective site
coefficients (Fa,eff) tend to underestimate responses depending on soil conditions. This discrepancy highlights the influence of basement inertial
effects and the need for further refinement. The study confirms the reliability of long-period site coefficients for basement response
predictions while identifying areas for improvement in short-period coefficient assessments. |
