Abstract
Natural period and damping ratio are important values in seismic design. Recently, many of the findings for these values have been
obtained from earthquake observation records. However, the observation records of buildings are affected by the soil–structure
interaction. Therefore, only the characteristics of the building structure are unclear. This study focused on the structural vibration
characteristics by using the records of large shaking table tests. Steel specimens subjected to strong input motion were studied, and
the experimental data were analyzed using the ARX model. Moreover, the effects of the experienced largest deformation on the
vibration characteristics were investigated.
