The increasing trend of mobile communications has seen exponential growth in the last three years. Increased competitions among mobile operators also have contributed to the installation of many towers to enhance both coverage area and network reliability. The tower locations as specified in terms of latitudes and longitudes with the height of mounted antenna dictated by functional requirements of the network. The availability of land which satisfies ideal installation conditions in urban areas is extremely limited. As a result the construction of tower requires exquisite engineering Skills Failure of such tower in a disaster like an earthquake and lateral wind load is major concern mainly in two ways. One is the failure of communication facilities will become a major setback to carry out rescue operations during disaster while failure of tower will itself cause a considerable economic loss as well as damages to human in most of the cases. Therefore, design of telecommunication towers considering possible extreme conditions is of utmost importance and a good design can considered as a step towards a greater degree of sustainability Their dynamic analyses are performed by ETABS software. The axial forces of the tower members are considered as the main parameter.
