The evolution of the telecommunications industry has resulted in the application of effective engineering of towers and mounts to allow for proper risk management and mitigation over the life cycle of telecommunication structures. With the recent publication of ANSI/TIA-222-I an additional step has been added to ensure the effective management of the loads being applied to the tower from the mount – the analysis of the ‘mounting system interface’, commonly referred to as MTI (Mount to Tower Interface). This PAN covers the evolution of structural analysis practices in the telecommunications industry, focusing on the importance of evaluating the Mount to Tower Interface (MTI) as outlined in ANSI/TIA-222-I. It explains the roles of different engineers in tower and mount analysis, details the data required for MTI evaluation, outlines calculation methods for lattice and monopole towers, and presents solutions for addressing overstresses. It also emphasizes the need for accurate, site-specific analysis to ensure structural reliability and compliance throughout the lifecycle of telecom installations.
