自由ロッキング振動から推定される衝突時の反発係数

It is important for overturning prevention of structure on seismic ground motion to understand characteristics of restitution coefficient at collision by free rocking vibration using small structure. In this study, characteristics of restitution coefficient at collision were investigated based on vibration experiments. In case that the restitution coefficient is constant, it was difficult to fit the free rocking vibration waveforms at later part between observed and numerical analysis. However, in case that the restitution coefficient are introduced nonlinear effects, they are good agree between them.
