On October 26, the Telecommunications Industry Association (TIA) TR-14 Communication and Small Wind Turbine Support Structures Committee published Revision H of the ANSI/TIA-222 Structural Standard for Antenna Supporting Structures and Antennas and Small Wind Turbine Support Structures.
Per the TIA: "Revision H represents a significant update to this important standard, which provides the industry with critical guidance regarding minimum load requirements and design criteria. More specifically, TIA-222-H addresses the requirements for the structural design and fabrication of new, and the modification of existing antenna supporting structures, antennas, small wind turbine supporting structures, appurtenance mounting systems, structural components, guy assemblies, insulators and foundations. The last update of TIA-222 (Revision G), which represented the most sweeping update to the standard, was published in 2006."
"Changes included in the newly published TIA-222-H standard include bringing it into alignment with the latest version of ASCE-7, use of ultimate gust wind speeds, updates to seismic loading considerations, to the design provisions in line with the latest AISC 360 steel design, climbing facilities, foundations, and analysis of existing structures. New annexes have been added including inspection of new construction or modification of existing structures and other informative annexes."
In an email to RadioWorld's Emily M. Reigart, National Association of Tower Erectors (NATE) executive director Todd Schlekeway said , “NATE is excited that the TIA 222 Rev H Standard is now available in the marketplace for the industry to utilize. The TIA 222 Rev H standard includes important updates pertaining to tower design, analysis, inspection, climbing facilities and weather impact that are extremely important in keeping the industry’s workforce safe when working at a communication tower site. Many subject matter experts from NATE member companies were involved in the development of TIA 222 Rev H and we thank them for their diligent efforts.”
“This is an important update to a standard that has become increasingly essential in our ever more connected world,” said Stephanie Montgomery, TIA’s vice president of technology and standards. “Revision H includes items that no related standard has previously addressed, making it a unique and vital resource. And because TIA-222 is supported by so many incredible companies and individuals, it represents a truly world-class standard.”
“The new Revision H builds on the previous Revision G and enhances the provisions and keeps the standard up-to-date and moving forward in addressing the industry needs,” added Mark Malouf, the task group chair who headed the revision effort.
TIA’s TR-14 committee, which includes representatives from over 100 companies, voted to approve and publish the revised standard during its meeting in New Orleans in August 2017. TIA submitted it to ICC for their review and inclusion into IBC 2018. Per a press release, "TIA thanks all members of the TIA-14 committee for their dedicated volunteer work that led to the publication of this essential standard. We especially thank the Task Group Chair and TR-14 Vice Chair, E. Mark Malouf, PE, SECB, IPF with Malouf Engineering Intl, and TR-14 Chair John Erichsen, PE, SE with EET."
The TIA-222-H standard is available from the TIA Standards Store via IHS.
