［摘要］龍卷風(fēng)是一種風(fēng)速極高，破壞力巨大的旋渦狀移動(dòng)風(fēng)暴，其所到之處會(huì)對(duì)構(gòu)筑物造成極其嚴(yán)重的影響。因此，對(duì)結(jié)構(gòu)安全性要求極高的核電廠(chǎng)設(shè)計(jì)時(shí)需考慮廠(chǎng)址地區(qū)龍卷風(fēng)事件的發(fā)生。結(jié)合實(shí)際工程，合理采用簡(jiǎn)化計(jì)算和有限元模擬計(jì)算相結(jié)合的方式對(duì)龍卷風(fēng)荷載作用下的核島構(gòu)筑物進(jìn)行了分析，結(jié)果表明，核島構(gòu)筑物具備足夠的能力抵抗龍卷風(fēng)的作用。

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.

Keywords： Tornado; missile; local effect; global effect
