Seismic Design Analysis of Nuclear Industry Pool Based on Response Displacement Method

Abstract

This article describes the basic principle and calculation method of displacement response method, and implemented in the large finite element commercial software ANSYS. The secondary development of ANSYS and the five point formula were used to obtain dangerous working conditions and internal force distribution of structure, and provide technical support for the industrial pool, a reasonable principal design section and distribution scheme. Numerical simulation shows that the side wall of the industry pool of the maximum moment is in the middle part of the middle and bottom. Under the same Seismic Design Category, the side wall bending moment under seismic action of SL1 is greater than the SL2. The internal force distribution of the column is obvious, and the middle of the industry pool has a maximum internal force. The deformation result of SL2 is larger than SL1 under the action of an earthquake, and the empty water status is a dangerous working condition. Adoption of appropriate measures can meet the aseismic requirements. The results of this paper provide a reference for the seismic design of nuclear power industry pools, or other similar engineering designs.
