【Abstract】 The seismic response analysis and exprimental study for five typical types of electrotechnical box of NPP have been completed. Structural free vibration characterization and seismic response were calculated by means of beam-plate linear mathematical model of finite element method. Seismic tests have been carried out for three typical types of electrotechnical box. Structural natural frequence and acceleration response from seismic tests were measured. Calculation results fairly meet test data. Thus effectiveness of the mathematical model is further verified.更多还原
