Abstract

Abstract: 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. Communication towers are playing vital role in this generation and in next. The main objectives of the present research work are i) To study and analyze the behavior of self–supporting Telecommunication tower for wind zones IV and V for Indian code practice IS 875 (part 3):2015. ii) To analyze the dynamic response of telecommunication tower for three ground motions occurred during earthquakes of 1940 Imperial Valley, 1957 San Francisco, and 1992 Landers. iii) To compare the results of analysis of telecommunication towers with different configurations. The experimental investigation consists of various tower like K-Bracing, V-Bracing, W-Bracing, XBX-Bracing, XX-Bracing of varies height 30m, 45m, 60m and varies zone like Zone-IV (50 m/s), and Zone-V (55 m/s). In this study it is found that for wind zone IV and V, tower height up to 30m, the displacement difference between XBX and W bracing is found to 56.82%. Also, for wind zone IV and V, tower height 45m and 60m, the displacement difference between K and XBX bracing is found to 41.20%. The analytical values are compared with experimental values, it is observed that analytical result is almost like experimental result. Further the present research investigation it was confirmed that K-bracing and XBX-bracing gives satisfactory result in wind analysis and time history analysis for considered wind zones and ground motions.Keywords: Telecommunication Tower, Seismic Analysis, Time History Analysis, Staad Pro
