各国架空导线设计风荷载计算对比分析

Comparison and Analysis of Design of Wind Load Calculation for OverheadConductors in Various Countries

对比现行国内外架空导线风荷载设计规范,结合具体算例分析了各国规范间的差异。相对于其他国家规范,我国规范风荷载设计值偏小,这主要是风振系数的差异造成的;在部分工况下,我国规范风振系数的计算值小于1,这意味着总的风荷载低于平均风荷载。

Comparing the current design codes for overhead conductor loads at home and abroad,the differences between the codes of various countries are analyzed with specific examples.Compared with the codes of other countries,the design value of the standard load in my country is relatively small,which is mainly caused by the difference of the wind vibration coefficient.In some working conditions,the calculated value of the wind vibration coefficient in my country′s code is less than 1,which means that the total wind load is lower than the average wind load.
