摘要：
Natural period and damping ratio are important values in seismic design because of their impact on the response of superstructures. However, observation records of buildings are affected by the soil-structure interaction (SSI). In this study, we propose a method to estimate the influence of SSI in horizontal and rocking direction and the vibration characteristics of the building itself. First, we verify the effectiveness of the proposed method for numerical analysis. Then, we apply the proposed method to a large shaking table test and evaluate the effect of each SSI according to the amplitude level. © 2023 Architectural Institute of Japan. All rights reserved.
