摘要
基于引雷空间理论,以矩形高层建构筑物为对象建立侧击雷击分析模型。通过将建构筑物尺寸、闪电先导取向角概率分布函数、所在地区雷电流极性与幅值分布特征等参数引入模型,提出量化与本地化程度较高的侧击雷击次数精确算法,并给出将本模型变换为计算其它形状建构筑物侧击通用模型的方法。
Based on Collection Volume Method （CVM）, the paper establishes a sideswipe lightning anal- ysis model of high-rise buildings. The exact algorithm for the number of sideswipe lightning which has more quantification and localization is obtained by introducing the parameters such as the building size, the probability distribution function of lightning leader orientation angle, and the local distribution char- acteristics of lightning current polarity and amplitude. Additionally, the transformation method for sideswipe general model of structures in other shapes is introduced.
