HawkinsDiscussion of Current Issues Related to Steel Telecommunications Monopole StructuresFatigue and Vortex Shedding Issues• Criteria for fatigue and dynamic effects from vortexshedding are not currently addressed in TIA-222-G.• AASHTO has fatigue criteria for highway structures, butmay not be appropriate for telecommunications poles.• ASCE Manual 72 (1990) and ASCE 48-05 Standard(2006) mention vortex shedding and fatigue but do notprovide specific criteria.• TIA TR-14.7 Subcommittee intends to address fatigueand vortex shedding criteria in future revisions of theTIA-222 Standard.• Additional research and testing is needed to developfatigue design criteria for poles.15 of 37
