【摘要】：考慮風(fēng)向的極值風(fēng)速估計(jì)是準(zhǔn)確估算建筑結(jié)構(gòu)風(fēng)荷載的基礎(chǔ),但迄今為止人們針對(duì)這一問(wèn)題的研究還不夠深入,尤其是各風(fēng)向極值風(fēng)速的相關(guān)性問(wèn)題研究較少。該文首先對(duì)Cook提出的獨(dú)立風(fēng)暴法進(jìn)行了改進(jìn),提高了風(fēng)氣候數(shù)據(jù)利用率,同時(shí)也使得研究各風(fēng)向極值風(fēng)速間的相關(guān)性成為可能;然后,通過(guò)分析不同風(fēng)向極值風(fēng)速之間的尾部相關(guān)性表明了良態(tài)風(fēng)氣候下不同風(fēng)向的極值風(fēng)速的漸進(jìn)獨(dú)立性,并開(kāi)發(fā)了一種新的考慮風(fēng)向的極值風(fēng)速估計(jì)方法;最后,通過(guò)南京地區(qū)各風(fēng)向極值風(fēng)速計(jì)算進(jìn)一步討論了該文方法的進(jìn)步之處。
[Abstract]:The estimation of extreme wind speed considering wind direction is the basis of estimating wind load of building structure accurately, but so far, the research on this problem is not deep enough, especially the correlation of wind direction extreme wind speed is less studied. In this paper, the independent storm method proposed by Cook is improved to improve the utilization ratio of wind and climate data, and it is also possible to study the correlation between extreme wind speed of each wind direction. Then, by analyzing the tail correlation between extreme wind speed of different wind directions, the asymptotic independence of extreme wind speed of different wind direction in good wind climate is shown, and a new method of wind speed estimation considering wind direction is developed. Finally, the advancements of this method are further discussed by calculating the extreme wind speed of each wind direction in Nanjing area.
