Risk Categorization in Accordance with ANSI/TIA-222-H and the 2018 IBC

By WIA Team

The ANSI/TIA-222 Standard and the IBC have traditionally adopted the methodology of the ASCE 7 Standard for determining the minimum loading requirements for new and existing structures. The ASCE 7 Standard has evolved since the publication of the ANSI/TIA 222-G Standard (Rev G). The release of Revision H of the ANSI/TIA-222 Standard (Rev H) in January 2018 and the publication of the 2018 International Building Code (IBC) brings these standards up-to-date with the latest ASCE 7 Standard (ASCE 7-16). The intent of this document is to provide clarity and insight regarding the Risk Category for a new or existing communication structure by comparing the risk categories from Rev H (Table 2-1) to the risk categories defined in IBC for buildings and other structures.
