Abstract: Two types of testing models, aero-elastic model and rigid pressure-measured model, were manufactured with reduced-scale ratio of 1:200 for some super large cooling towers located in the Southeast coastline. For various tower distances, incoming wind angles and field conditions, distributions of wind-vibration factors along cooling tower structures are compared by the aero-elastic model tests in TJ-3 wind tunnel. In the light of actual combination of tower groups and adjacent other buildings, the effect of complicated terrain conditions to group towers factors and wind-vibration factors are studied using the rigid model and aero-elastic model, respectively. Results show that the effect from other buildings with the same dimension as cooling towers cannot be neglected safely. The above conclusions are also compared with the corresponding items in Chinese cocles, and some suggestions to improve items in cocles are finally proposed.
