Comparative Analysis and Structural Design of Transmission Line Towers under Wind Loading
Main Article Content
Abstract
Transmission line towers are critical structural components of electrical power transmission systems and are required to withstand various environmental and operational loads throughout their service life. Among these, wind loading is one of the most significant lateral loads influencing the structural stability, member forces, deformation, and overall safety of transmission towers. This study presents a comparative analysis and structural design of transmission line towers subjected to wind loading. The analysis considers the major design parameters, including tower geometry, material properties, wind speed, terrain conditions, exposure characteristics, and load combinations. Wind loads acting on the tower and conductors are evaluated according to relevant structural design provisions, and the resulting forces are used for the analysis and design of tower members. The structural response is assessed in terms of axial forces, stresses, displacement, reactions, and factor of safety.
A comparative evaluation is performed to identify the influence of different wind-loading conditions and structural configurations on the performance of transmission line towers. The study aims to determine the most suitable tower configuration by achieving an appropriate balance between structural strength, stability, safety, and material utilization. Numerical structural analysis can be carried out using engineering software such as STAAD.Pro or ANSYS to evaluate the behavior of the tower under critical loading conditions. The findings of the study provide useful insights into wind-resistant transmission tower design and can assist in developing safe, reliable, and economically efficient transmission line structures.
