ABSTRACT
Received 3 May 2020 Accepted 4 October 2020 Published Online 17 December 2020
The Telecommunications Industry Association (TIA) is responsible to provide recognized literature for the analysis & design of communication towers. TIA in 2005 released a standard “TIA-222-G” which has gained a widespread reference and most of the existing tower structures around the world have been constructed as per guidelines of this standard. However, in 2018, TIA released the latest standard TIA-222-H. To date, not much studies are available describing how much change in member axial forces occurs while using latest standard for analysis of tower structures. The main objective of this study is to provide guidelines for wind load calculation on tower body, appurtenances and other structures and to compare the member axial forces induced by the wind loads as per TIA-222-G & TIA-222-H standards. The analysis results show that member axial forces are not much affected when the tower was analyzed in accordance with both the standards. However, forces might increase when the basic wind speed increased more than 200 kph as per TIA-222-H standard.

1. Introduction With the revolutionary development in telecommunication sector, lattice type steel structures have been largely installed around the world to facilitate wireless communication (Kemp and Behncke, 1998). The literature review indicates that the best type of communication towers are self-supporting towers with having large face widths greater than or equal to the diameter of the mounted dishes (Albermani et al., 2009). Analysis & design of the tower is not a straightforward process but an interactive compromise between many factors, which must ultimately satisfy basic strength requirements (Alam and Santhakumar, 1996; Albermani et al., 2004). The Telecommunications Industry Association (TIA) which is accredited by the American National Standards Institute (ANSI) develops TIA-222 standards. The objective of these standards is to provide recognized literature for cellular towers, data terminals and smart utility networks etc. The literature is provided pertaining to: 1) minimum load requirements as derived from ASCE 7-16 (2016), 2) design criteria as derived from AISC-360-16 (2016) and building code requirements for structural concrete (ACI 318-14, 2014). TIA in 2005 released a standard TIA-222-G namely “Structural Standard CORRESPONDENCE Mohsin Usman Qureshi ⓒ 2020 Korean Society of Civil Engineers
