Static and Dynamic Analysis of Trasmission Line Tower

he present paper deals with the study of static and dynamic analysis of transmission line tower (X type of bracing system). A typical type of transmission line tower carrying 220KV single circuit conductor is chosen as case study existing in bijapur district. The analysis and modeling of tower is carried out using FE based ANSYS software. The model is created in CATIA and then imported to ANSYS workbench. The loads acting on the tower considered are dead load, live load and dynamic loads (Seismic and wind). The existing tower has height of 40m, which includes ground clearance, maximum sag of the conductor, vertical spacing between conductor wire. Static and dynamic analysis is carried out in detail using FE based ANSYS software. Static, modal, response spectrum and wind analysis is performed. Response spectrum analysis is carried out for 0.3g, 0.4g, 0.5g ground accelerations by considering DBE (Design basis earthquake) for earthquake zone III. Wind zone considered is zone III. The wind pressure depends on the gust response factor, which increases with height. The behavior of existing tower (X type of bracing) is analyzed for different analysis. The maximum deformation, combined stresses, natural frequencies and direct stress are obtained and plotted graphically. Keywords— Dynamic, Static, Seismic, Tower, Wind
