Subject Area:

Physical Sciences and Engineering

Abstract:

The major system providing lateral load resistance in steel telecommunication towers is bracing system. There are different types of bracing systems for steel towers. The heights of these towers in Ethiopia vary from 20 to 102 meters, based on the practical requirements. This study has focused on identifying the economical bracing system for a given range of tower heights. Towers of height 35m, 45m and 50m have been analyzed and designed with different types of bracing systems under seismic and wind loads. Based on the seismic zones and worst wind speed of Ethiopia the optimal bracing system has been identified and reported.
