INFLUENCE OF STRUCTURE CHARACTERISTICS ON EARTHQUAKE RESPONSE UNDER DIFFERENT POSITION OF ROOFTOP TELECOMMUNICATION TOWERS

In today’s era the mobile sector is growing dynamically & the trend of mobile communication is increasing day by day. Generally for telecommunication purpose, the four legged supporting tower are used widely. In the last few years there has been tremendous increase in the communication industries which result in the installation of large number of tower for consistency of network and to increase the coverage area. The availability of land in urban areas is extremely limited for satisfying the ideal installation of tower thus giving no alternative but to adopt roo f top towers. As tower plays a significant role for wireless communication network, the failure of such structure in a disaster is a major concern therefore utmost important has been given considering the seismic effect acting on the tower. Firstly, the seismic effect is considered at the different types of soils and in the last, we considered the position of tower at roof top of structure, and it is observed that the displacement is different at various height of structure i.e. the displacement is maximu m at the top height of tower and minimum at building. The results obtained from the above analysis are tabulated, compared and conclusions is drawn that as observed the displacement is minimum in soft soil, & displacement is minimum when the position of to wer is at the centre of structure
