Geospatial study for wind analysis and design codes for wind loading: A review

Abstract

Transmission line is one of the crucial components in power networking system for a Nation. Breakdown of the line caused by the structure failure absolutely will disrupt the power networking system. In order to avoid any irregularities, the factor that will contribute to the structural failure should be determined and analysed. Wind load is one of the factors that are taken into account by the design code in load design calculation of transmission tower. This paper presents study on geospatial analysis in analysing wind data and application of design codes used to calculate wind load imposed to structure. Previous study has been reviewed to understand what have been implemented by previous researcher on the application of Geospatial Analysis to the wind data. It is found that Geospatial Analysis have been applied to analyse the wind data by considering a few factors such as elevation, topography factor, terrain roughness factor and others. The design codes such as MS 1553 Malaysian Standard, EN 503411 CENELEC and ASCE 74 as well have been studied in order to understand the calculation of wind load on the structure design.
