Abstract

Abstract: The increasing trend of mobile communications has seen exponential growth in the last three years. Increasedcompetitions among mobile operators also have contributed to the installation of many towers to enhance both coverage areaand network reliability. The tower locations as specified in terms of latitudes and longitudes with the height of mountedantenna dictated by functional requirements of the network. Communication towers are playing vital role in this generationand in next. The main objectives of the present research work are i) To study and analyze the behavior of self–supportingTelecommunication tower for wind zones V and VI for Indian code practice IS 875 (part 3):2015. ii) To analyze the dynamicresponse of telecommunication tower for three ground motions occurred during earthquakes of 1940 Imperial Valley, 1957San Francisco, and 1992 Landers. iii) To compare the results of analysis of telecommunication towers with differentconfigurations. The experimental investigation consists of various tower like K-Bracing, V-Bracing, W-Bracing, XBXBracing, XX-Bracing of varies height 30m, 45m, 60m and also varies zone like Zone-V (50 m/s), and Zone-VI (55 m/s). Inthis study it is found that for wind zone V and VI, tower height up to 30m, the displacement difference between XBX and Wbracing is found to 56.82%. Also for wind zone V and VI, tower height 45m and 60m, the displacement difference between Kand XBX bracing is found to 41.20%. The analytical values are compared with experimental values, it is observed thatanalytical result are almost similar to experimental result. Further the present research investigation it was confirmed that Kbracing and XBX-bracing gives satisfactory result in wind analysis and time history analysis for considered wind zones andground motions.Keywords: Telecommunication Tower, Seismic Analysis, Time History Analysis, Staad Pro.
