Background: Seismic test analysis of a cabinet in 18-5 citical device building is requried for safety inspection of zero power reactor

however

the floor response spectra at the height of 3.5 m where the cabinet is located are lacking.Purpose: For seismic test analysis of the cabinet in 18-5 citical device building

dynamic analysis is performed for the building

with the purpose to obtain the floor response spectra at the height of 3.5 m where the cabinet is located.Methods: The displacement time history and acceleration time history on the given height floor are calculated by using transient dynamic time history method with the software ANSYS under the load of foundation displacement time history

then acceleration response spectrum on the floor that the cabinet locates is calculated with the corresponding acceleration time history obtained on the cabinet floor.Results: The design floor response spectra under load OBE and SSE at the height of 3.5 m are offered with damping ratios of 2%

4%

5% and 7%

respectively.Conclusions: The design floor response spectra are credible and have been adopted by test analysis of the cabinet.
