IEC、ASCE、GB50545规范风压高度变化系数对比与分析

Contrast and Analysis on Wind Pressure Height Coefficient about IEC、ASCE、GB50545 Criterion

通过对输电线路国际标准《Design criteria of overhead transmission lines》(IEC 60826-2003)、美国标准《Guidelines for Electrical Transmission Line Structural Loading》(ASCE74-2009)和我国标准《110kV～750kV架空输电线路设计规范》(GB50545-2010)关于风荷载计算中风压高度变化系数的对比与分析,理清各标准之间风压高度变化系数的差异、便于设计人员对IEC、ASCE标准的理解和运用。

The difference of wind load calculation between IEC,ASCE,GB codes was introduced in this paper.Through comparing and analysising the difference of wind load calculation,the purpose is to helf the designer to better understand and apply different standards.
