The safety of nuclear power structure is very important. The establishment of a refined fine finite element model is beneficial to the dynamic analysis of nuclear power structure, but it brings challenges to the computational efficiency. In this paper, a self-developed finite element software based on multi-GPU parallel explicit algorithm (GFE) is firstly introduced. Using the GFE software, dynamic response of nuclear power structures considering soil-structure interaction (SSI) under seismic load is analyzed and compared with the commercial software. The calculation results show that the results obtained from the GFE software is consistent with that obtained from the commercial software. Compared with the general commercial software, the GFE software has higher computational efficiency. The calculation time of GFE software for the seismic analysis is respectively about 1/7 that of the general commercial software.
Key words: Nuclear power structures / GFE software, seismic analysis / Soil-structure interaction
