Revision H Standard: One Year Later

The AEC podcast interviewed FDH’s Dennis Abel, PE, Chief Engineer, to discuss the implications of the Revision H standard on the tower industry one year since its October 2017 publication. Officially titled “ANSI/TIA-222-H: Structural Standard for Antenna Supporting Structures and Antennas and Small Wind Turbine Support Structures,” the standard, which became effective January 2018, provides guidance on minimum load requirements and design criteria. Revision H creates changes relating primarily to wind loading, existing structures, steel and concrete strengths, seismic analyses, mount analyses, and inspections and mappings.
