N2 - This study investigated the sensitivities of the anti-resonance frequencies (ARF) in floor vibrations in buildings. The application of ARF to protect nonstructural elements in earthquake environments was proposed and found effective for fixed end building types in previous studies. The effect of Soil-Structure Interactions (SSI) during seismic motion was investigated. A simplified method to locate the ARF of a shear-type building in an SSI environment is proposed. Analytical models were used to show the accuracy of the proposed method. To investigate the sensitivities of ARF on various floors in a building to different soil and foundation types, analytical models were built for analysis. It was found that in soils with low shear wave velocities, the first mode ARF could be extensively influenced. However, higher mode ARFs’ were insensitive to the variations in foundation conditions. This result suggested that engineers exercise caution in choosing the first mode ARF for the seismic protection of nonstructural elements if the soil is weak.
