Abstract

We use the finite element method to analyze the seismic design of a liquid storage tank for a polar crane at a nuclear power plant. We obtained the natural frequency and vibration modes by modal analysis, and we evaluated the seismic stability by response spectrum analysis. Furthermore, the seismic analysis of the tank was accomplished by analyzing not only the forces applied to the wall by the sloshing of the liquid, but also the safe-shutdown earthquake condition for the tank. We propose a seismic-design process and a seismic-analysis method for liquid storage tanks based on the commercial finite element analysis program, ANSYS.

본 논문에서는 원자력 발전소 폴라 크레인(polar crane)의 설계를 위해 유한요소법을 통한 내진해석을 수행하였다. 모드 해석(modal analysis)을 통하여 폴라 크레인의 고유진동수와 진동형상을 파악하고 응답스펙트럼(response spectrum)을 통해 폴라 크레인의 내진 안전성을 평가하였다. 그리고 액체저장탱크에 대한 내진해석을 유한요소법을 이용하여 수행하였는데, 탱크가 요동시에 액체가 탱크 외벽에 가하는 힘을 고려한 슬로싱해석과 안전정지지진 하중 조건에서의 해석을 수행하였다. 본 논문에서 유한요소해석 상용코드인 ANSYS를 이용하여 내진해석에 필요한 해석기법과 과정 등을 설계 시에 활용할 수 있도록 제안하였다.
