Abstract：Based on the prototype of transfer and purging rooms in nuclear power plants, the finite element models of transfer and purging rooms without a cantilever and with a cantilever were established. Based on the modal analysis and dynamic time history analysis of the two models, the influence of the cantilever on the seismic performance of the transfer and purging rooms was analyzed, and the dynamic characteristics and seismic performance of the transfer and purging rooms were discussed. The results show that the structural stiffness of the transfer and purging rooms is great, the natural vibration period is short, the seismic response is small under the excitation of ground motions beyond the design standard, and the whole structure is still in an elastic state. The large cantilever in the structure obviously reduces the stiffness of the transfer and purging rooms, prolongs the natural vibration period of the structure, and increases the overall seismic response of the structure, but the amplification is not significant. And the transfer and purging rooms with a cantilever fully meet the requirements of seismic performance.
