Abstract:The seismic properties of the structure with suspending coal hoppers and the structure with supporting coal hoppers are studied by the method of elasto-plastic time history analysis with ANSYS. Through a comparative analysis, theresults show that the structure with suspending coal hoppers has a distinct effect on reducing the seismic response of the thermal power plant.

Keywords:suspending coal hoppers; vibration reduction; seismic response
