INFLUENCE OF TELECOMMUNICATION TOWER ON RESPONSE OF HOST STRUCTURE
Abstract
In the contemporary era, the telecommunication industry plays a great role in human societies and thus much more attention is now being paid to telecommunication towers than it was in the past. As telecommunication tower are the only means of enhancing both the coverage area and network reliability more and more telecommunications tower are installed nowadays. The direction and height of tower along with the antennas mounted on it is completely governed by the functional requirements of network. The most ideal place for tower is on ground but in urban areas the availability of land which would be most ideal is extremely limited giving no alternative but to adopt rooftop tower with marginal adjustment in terms of position. In this present study, the seismic analysis of 4 legged angled section rooftop telecommunication tower has been studied under the effect of design spectrum from Indian seismic code of practice for zone-iii along with wind analysis as per IS 875 (part 3) 1987. The analysis has been performed on tower located on roof of host structure by varying the positions of tower in Etabs software. The stresses in beam grid of rooftop tower foundation, stresses in host structure, retrofitting in host structure, axial forces in tower are the main parameters considered for the study. The host structure also analyzed with flexible base, to see the effect of flexibility of soil on host structure and tower response.References
