Demand for warehouses is increasing as logistics are globally expanding. This demand comes with an increasing requirement for warehouses to be cost effective and seismic proof, with the capability of preserving their contents. To meet these requirements effectively, the application of “sliding effect” to the structural design of warehouses is one option that can be used. Sliding effect is a technique that has attracted attention to reduce the seismic response of a building and load by sliding loads during an earthquake. The effectiveness of the sliding effect for structures under fixed base conditions has been confirmed through the experimental and analytical results of previous studies. However, this has yet to be confirmed in the case of considering soil-structure interaction (SSI). In this study, a large three-story warehouse is trial designed, and parametric studies considering SSI using modified Penzien model, which can analyze non-linear behavior, are conducted. Furthermore, additive equivalent damping factor hae, which converts the response reduction value into an additional damping factor, is calculated. The results show that although the response of the SSI model does not match that of the base fixed model, the SSI model has a sliding effect equivalent to the base fixed model, and more than 6% high hae are calculated.
