抄録

Hitherto, the overturning of rigid bodies under earthquakes have been dealt with in terms of the maximum ground accelaration and the maximum ground velocity. However, the adequate estimate for all shapes and sizes of rigid bodies has not been established yet. In this paper, the energy approach is applied to the overturning problem. By introducing the equivalent period of vibration, the energy inputs to rigid bodies are estimated based on the energy spectrum. The possibility of overturning is judged by equating the energy input to the potential energy of rigid bodies on the brim of overturning.
