【摘要】:為研究核電站結(jié)構(gòu)-設(shè)備相互作用的地震反應(yīng),針對某高溫氣冷堆核電站反應(yīng)堆進行結(jié)構(gòu)與設(shè)備相互作用的地震反應(yīng)分析研究,通過對考慮與不考慮結(jié)構(gòu)-設(shè)備相互作用的模型進行對比,開展模態(tài)分析、設(shè)計基準地震動下和超設(shè)計基準地震動下的動力特性分析以及樓層反應(yīng)譜分析,結(jié)果表明:考慮剪力墻主體結(jié)構(gòu)與設(shè)備的相互作用后,結(jié)構(gòu)的地震反應(yīng)減小,層間剪力最大減小60%,水平向樓層反應(yīng)譜峰值減小為不考慮相互作用時的40%,提高了結(jié)構(gòu)與設(shè)備的安全性,并為設(shè)備抗震設(shè)計提供依據(jù)。但豎向樓層反應(yīng)譜在結(jié)構(gòu)豎向周期附近有放大作用,建議在設(shè)備抗震設(shè)計時予以注意。
[Abstract]:In order to study the seismic response of structural equipment interaction in nuclear power plant, the seismic response analysis of the interaction between structure and equipment in a nuclear power plant reactor of a high temperature gas cooled reactor is studied. By comparing the model considering the interaction between the structure and equipment, the modal analysis is carried out, and the base ground motion and the super design datum are designed. The dynamic characteristic analysis and the floor response spectrum analysis show that, after considering the interaction between the main structure and the equipment, the seismic response of the structure is reduced, the maximum interlayer shear force decreases by 60%, the peak of the horizontal floor response spectrum decreases to 40% when the interaction is not considered, and the safety of the structure and equipment is improved. It provides a basis for seismic design of the equipment. However, the vertical floor response spectrum has amplification effect near the vertical period of the structure, so it is recommended to pay attention to the aseismic design of the equipment.
