Beschreibung
Zusammenfassung:	The invention discloses a cross arm hanging point load calculating method under the fluctuating wind effect during transmission line windage yaw. The method comprises the following steps: 1, solving the chordwise tension H of a power transmission line under the average windage yaw state through iteration; 2, solving the dynamic tension DH under the fluctuating wind effect; 3, solving the end tension of the power transmission line. By means of the Cross arm hanging point load calculating method under the fluctuating wind effect during transmission line windage yaw, the influence of the dynamic tension caused by fluctuating wind to the two ends of the power transmission line can be considered during tower structure load calculation in transmission tower design, and it is of great significance in enhancing the tower bearing capacity and ensuring safety operation of a power grid.
