Analysis of Rooftop Telecommunication Tower with Base Isolation

The increasing trend of mobile communications has seen exponential growth in the last three years. The communication industries have seen a tremendous increase in last few years which have resulted in installation of large number of towers to increase the coverage area and network consistency. The availability of land which satisfies ideal installation conditions in urban areas is extremely limited giving no alternative but to adopt roof tops. In this present study, the seismic analysis of 4 legged self-supporting rooftop telecommunication towers has been studied under the effect of wind analysis as per IS 875 (part 3): 1987 along with seismic forces under Indian seismic code of practice. In this dissertation, the forces developed due to wind as well as dynamic analyses are considered and the base isolation is to be provided to the structure to overcome them. In the following study stresses in rooftop tower foundation, stresses in host structure, axial forces in tower are the main parameters considered for the study.
