Loading Analysis of a Typical Electric Pylon

51 www.ijerm.com  Abstract— Electric pylon is a structure made of steel having relatively high ratio for its length and width. The structure is strong enough to withstand gravity and several type of external forces. Electric pylon is one of the vital components of electric transmission line that make a transmission tower. The tower must be reliable and able to operate under several loading conditions. Environmental loading contributes the largest percentage of the total loads experienced by any typical tower structure. This paper investigates the loading condition usually experiences by typical pylon structure. The structure modeling is done using finite element software. The influence of various loading conditions on the structure is investigated and the critical elements of the tower structure are determined. From the result obtained, it shows that the most critical element is bracing member situated on the lowest level of the pylon structure. The result of this study also shows that the safety level in the entire structure is acceptable under all the most severe loading conditions.
