Abstract:

Based on the basic principle of high-frequency force balance assumption of pulse wind loads, the spatial distribution of wind loads on numerical analysis is conducted on the crossing tower ZVK of the （HFFB） technique and the quasi-steady the transmission tower is estimated. Then, Xiangjiaba--Shanghai , Jinping--Sunan ＋ 800 kV ultra-high voltage （UHV） transmission project now being constructed, and the effectiveness of this proposed method is verified. Calculated results show that the proposed method extends the HFFB test reliably and feasibly because it well reveals the spatial distribution of wind loads on the transmission tower.

Key words: wind tunnel test, high-frequency force balance test, wind load, spatial distribution, ultra-high voltage, transmission tower
