Abstract

This paper described the application of Geospatial Analysis in determining mean wind speed, for wind load calculation imposedto electrical transmission tower structural design. The basic wind speed data on available station obtained from Malaysian Meteorology Department is adjusted by considering terrain and ground roughness factor. The correlation between basic wind speed, terrain factor and ground roughness stated in EN-50341-1 is used to obtain the for overhead transmission line elements 50 m above ground. Terrain factor, and ground roughness, in this study are presented by land use types of study area. Wind load is then calculated by using equation stated in design code EN-50341-1 by using the adjusted mean wind speed. Scatter plots of for different and are presented in this paper to see the effect of these parameters to the value of . Geospatial analysis is used to represent the model of . This model can be used to determine possible area that will subject to wind load which severe to the stability of transmission tower and transmission line.
