Abstract
Electric Power Development Co.Ltd. is now building coal-fired thermal power plants at Tachibana-cho. Anan-shi in Tokushima prefecture. In the project, they planned to build eight (8) large-sized silos for coals whose capacity are 70,000 tons weight. When we designed coal-silos for earthquake loads, we should consider interaction between coals and structure. Damping forces of coals become large in inelastic region of their strain and coal absorbs a lot of seismic energy. We confirmed structural safety of silos to big ground motions by the design method considering inelastic behavior of coals.
