This paper establishes a complete finite element model by ANSYS software for the storage device of the containment device gate, and analyzes the structural strength of the device gate storage device under the OBE seismic condition. In the model, the shell element is used to model the device gate assembly and storage device, so as to simulate the whole structure under actual working conditions, and analyze the seismic performance of the device gate storage device. The results show that under OBE seismic conditions, the whole steel structure of the storage device and the strength of all connecting bolts meet the requirements of RCC-M specification. In this paper, the seismic performance of the equipment gate storage device is studied by means of finite element analysis, modal analysis and response spectrum analysis. This method has certain significance to the seismic design and checking of the equipment gate storage device, and it is applicable to the seismic design of the spent fuel dry storage device.
