Abstract
Wind characteristics by the undulated topography is one of the most important items to evaluate wind loads for structures. This paper describes the result of wind tunnel tests of some fundamental escarpment and the area, where some transmission pylons are turned over at the typhoons 9117 and 9119. The models of fundamental escarpment changes its slope angle, height, surface roughness and approaching flow conditions. The obtained data indicates that the surface roughness affects a lot for the mean wind speed distribution, although the gust wind speed does not change. From the wind tunnel test of the actual area, the wind is found to be affected by both speed-ups by ‘escarpment’ and large-scale turbulence due to vortices from the upstream steep hill.
