We implemented a simplified analysis method to capture the seismic behaviors of structures. In the simplified method, the soil-foundation system is replaced by a nonlinear rotational spring, a linear rotational dashpot, and linear horizontal spring and dashpot based on a simplified analysis method introduced by Anastasopoulos and Kontoroupi (2014). In order to investigate the applicability of the simplified method, we compared analysis results with 1-g shaking table tests having a building with a square-shaped spread foundation placed on soft clay soil. This comparison revealed that the simplified method could capture the response of the building during dynamic loading, although it has some limitations.
