[摘要]龍卷風是一種風速極高,破壞力巨大的旋渦狀移動風暴,其所到之處會對構筑物造成極其嚴重的影響。因此,對結構安全性要求極高的核電廠設計時需考慮廠址地區(qū)龍卷風事件的發(fā)生。結合實際工程,合理采用簡化計算和有限元模擬計算相結合的方式對龍卷風荷載作用下的核島構筑物進行了分析,結果表明,核島構筑物具備足夠的能力抵抗龍卷風的作用。
[關鍵詞]龍卷風; 飛射物; 局部效應; 整體效應

Abstract: Tornado is a spiral shaped moving storm with high speed and enormous destructive power, all the buildings on the route of tornado will be heavily affected. So, the design of nuclear power plant with extreme high safety requirement should consider the occurrence of the tornado event. Simplified method and finite element method was properly adopted in the analysis and design of nuclear building under the tornado loads, and all the design parameters were taken from real project. The analysis result shows that the nuclear building is of the capability to resist the tornado loads.
