Abstract

Abstract

Based on the primary nonlinear system of the nuclear plant,a primary seismic analysis was completed with ANSYS software.The results show that the load is conservative using directly Rayleigh damping.If the calculation method is permission,using the modal damping can decrease the conservativeness of seismic loads and improve the economy of the plant.
