EIA/TIA-5053:2017

This Standard addresses requirements for mounting systems supporting antennas and related appurtenances. The requirements for rigging or for climber anchorage are not within the scope of this Standard. Loading combinations are provided in this Standard for the structural design of mounting system members and their connections for the purpose of establishing mount classifications. All mounting systems regardless of classification, may be investigated in accordance with TIA-222 or this Standard for specific applications. The loading combinations provided in this Standard specify maintenance loads for certain mount classifications. All construction activities, including maintenance, associated with a mounting system shall be defined in a rigging plan and shall be supervised on-site by a Competent Rigger in accordance with ANSI/ASSE A10.48, 'Criteria for Safety Practices with the Construction, Demolition, Modification and Maintenance of Communication Structures' (ASSE A10.48). A sitespecific structural analysis of a mounting system may be required by a Qualified Engineer based on the loads provided in a rigging plan. The determination of strength requirements for a supporting structure including the investigation of local stresses at mounting system connections to the supporting structure are not within the scope of this Standard and shall be investigated in accordance with TIA-222.
