In thermal power plant, steam is made by boiler. As it rotates turbine, electric power is generated. Thermal power plant has a high-rise structure that has a boiler and other equipment. Thermal expansion of the boiler is large because combustion temperature is high. The boiler vibrates easily because it is suspended from the top of the support structure in order not to restrict deformation by thermal expansion. Thus, the boiler structure supported by the hanger is very vulnerable to earthquakes. In this study, numerical analysis was carried out in order to investigate behavior of the boiler structure in the thermal power plant under earthquakes.
