摘要
Abstract
An accurate determination of wind loads is a key element of the transmission tower design.The selection of the wind load distribution coefficient has a direct impact on design specifications of the tower.This paper reviews and analyzes the principles for calculating the wind load on the tower body and the cross-arm in accordance with the design standards.Based on the analysis of the wind load on the tower body and the cross-arm following IEC60826 and BS50341 standards,a calculation formula for wind load distribution coefficient is derived with 0-360 wind angles and the wind load distribution coefficients are calculated for different projected area ratios.In addition,the characteristics of the wind load distribution coefficient of the tower body and the cross-arm are analyzed and compared.Through the research,the characteristics of transmission tower wind load distribution coefficient are developed and the results can be used as references for the transmission tower design.关键词
