“…For the purpose of design, the wind loads of transmission towers consist of transversal direction and the longitudinal direction of transmission lines. The method of calculation of the wind loads under skewed wind loading for transmission towers needs to be studied, as it plays an important role in the structural design of the towers (Yang et al, 2015). Besides that, forces on building elements as well affect the wind action.…”

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.

“…For example, (Caracoglia et al [4]) and (Bobby et al [5]) evaluated slender buildings, (Ambrosini et al [6]), (Belloli et al [7]) and (John et al [8]) evaluated chimneys, (Tamura et al [9]), (Henriques et al [10]) and (Koss et al [11]) evaluated towers and masts, (Ke et al [12]) evaluated cooling towers and (Yang et. al [13]) studied the behavior of transmission towers subjected to wind. (Franco [14]) developed a procedure the "synthetic wind" method for the calculation of gust factor, acting in the position of the gust center of the structure, position obtained deterministically.…”

Usually, the analysis of structures under wind loading is performed using an equivalent static analysis, where the influence of floating response is taken into account by the gust factor. This methodology can be used in case of rigid structures for not presenting a considerable dynamic response. More flexible structures, in particular those lightly damped, may show an important resonant response and their dynamic properties must be considered in the analysis. The aim of this paper is to present a methodology for dynamic analysis of structures under wind loading considering the geometric nonlinearity, the vibration caused by the kinetic energy of wind gusts and the aerodynamic damping due to the relative movement between this structure and the wind. The formulation proposed is applied to a 180-meter-high concrete chimney and the results were compared with those obtained through the recommendation given in the standard ABNT NBR 6123:1988 [2] for the dynamic structural analysis.

“…The response of the aeroelastic model of the single span transmission line exposed to the wind action in the atmospheric boundary layer was investigated in the wind tunnel and described in [20]. Wind tunnel tests on the behavior of two models of top segments corresponding to cross-arms of the transmission tower were carried out by authors of [21].…”

Abstract. The paper presents FEM analysis of the wind action on overhead transmission power lines. The wind action is based on a stochastic simulation of the wind field in several points of the structure and on the wind tunnel tests on aerodynamic coefficients of the single conductor consisting of three wires. In FEM calculations the section of the transmission power line composed of three spans is considered. Non-linear analysis with deadweight of the structure is performed first to obtain the deformed shape of conductors. Next, time-dependent wind forces are applied to respective points of conductors and non-linear dynamic analysis is carried out.
