大型火力発電施設の制振構造に関する研究

抄録

Japan is an earthquake-prone country. The 2018 Hokkaido Eastern Iburi earthquake damaged a coal-fired thermal power plants in Hokkaido and caused an electric outage throughout Hokkaido. Therefore, it is important to improve the seismic resistance of thermal power plants. In addition, the boiler of coal-fired power plants has a large and complicated shape, and it is necessary to model it based on actual measurement to evaluate the seismic response. Therefore, the purpose of this research is to improve seismic resistance by attaching multiple vibration damping devices to the boiler structure of coal-fired power plants to impose reins on the response during an earthquake. Also, the purpose is accuracy improvement of model.
