The July 2018 issue of AGL Magazine features an article from FDH’s Dennis Abel, PE, director of engineering, on “Existing Structures Specifications in TIA-222-H.”
The article is the second in a series of three articles on the implications of Rev. H for carriers and tower owners, authored by Abel, who is a member of the TR-14 Committee that developed the TIA-222-H design standard.
In the second article, Abel explains the four types of changed conditions that trigger the requirement for a structural analysis, along with acceptable stress levels and other topics in Section 15 of TIA-222-H.
The first article, released February 2018, addresses Wind Loading Changes in Rev. H. The third and final article in the series is expected to be published in October 2018.
The new standard, titled “ANSI/TIA-222-H: Structural Standard for Antenna Supporting Structures and Antennas and Small Wind Turbine Support Structures,” was published October 2017 and became effective January 1, 2018.
