Electrical transmission line is it medium to carry power loads from one station to another station, therefore, it is one of the most important projects in power business. To maintain the reliability and safety of' the structure, the dynamic and static load acting on transmission structure should be thoroughly studied before an efficient design may be obtained. I ligh standard of design to cater effect of wind load must be implemented to preclude any structural Ihilure which will interrupt the national grid supply of power. The main objective of this study is to identify the behavior of electrical transmission tower due to lateral wind forces. In addition, this study aims to evaluate current design practice adopted by Tenaga Nasional Berhad (TNB) on its adequacy and in optimization of their design. The study begins with comprehensive research and literature review on behavior of transmission tower and conductor under wind loads. A 132kV electrical transmission tower is identified for the purpose of analysis. The calculation of design wind loads are in accordance with American Society of* Civil Engineers (ASCE) 7-05 Minimum Design Loads for Building and Other Structures. The electrical transmission tower is assumed located at mountainous area with it wind speed of' 38 m/s and assessed as a global structure under normal situation as well as under broken conductor situation. As the outcome of the analysis, it design assessment of the transmission tower is provided. Subsequently, the reliability of' TNB current practice of design and the design adequacy is evaluated.
