摘要

This paper introduces the basic principle and calculation method of displacement re- sponse method, and implements in the large finite element commercial software ANSYS. We study the internal force distribution under different conditions of the industrial pool. Through the secondary development of ANSYS and the five-point formula we obtain the internal force distri- bution of structure under the critical working condition, and provide technical support for the in- dustrial pool. Numerical simulation shows that the maximum bending moment of the side wall of the industry pool is in the middle part of the middle and bottom. Under the same seismic design category, the side wall bending moment under the action of SL1 is greater than that the SL2. The internal force distribution of column is obvious, and the middle of the industry pool has a maxi- mum internal force. The deformation due to SL2 is larger than that due to SL1, and in the empty status the working condition is critical. Adoption of requirements. The results of this paper can provide power industry pools, or other similar engineering. appropriate measures can meet the aseismic a reference for the seismic design of nuclear
