Engineering Committee TR-14 is responsible for the ANSI/EIA/TIA-222, Structural Steel Standards for Steel Antenna Towers and Supporting Structures standard. Work is underway to define changes for the standard’s next revision of ANSI/EIA/TIA-222, with plans to align the standard with the latest version of ASCE-7. Use of 3-second gusts instead of fastest mile wind speeds and the use of load reduction factor design instead of allowable stress design will be incorporated. Other anticipated changes include: seismic loading considerations, safety facilities, foundations and analysis of existing structures.
