- 2.6.7.4 Gust Effect Factor for Structures Mounted on Other Structures
(344484 views) - Approximately when will the next revision or amendment to 222 be? What are the top two or three major changes being contemplated? Will 222 be aligned with ASCE 7-2010 (yes, I'm aware of the FAQ related to this)? Has there been any discussion of aligning 222 wind pattern provisions with those of EN 1993-3-1 and C37?
(548281 views) - As everyone is aware, many jurisdictions are now adopting the IBC 2012, which has updated wind speed maps. Regarding TIA-222-G, can the converted (Vasd) wind speeds from the IBC 2012 be used instead of the wind speeds listed in TIA-222-G, or do we need to take the more stringent of the two? I know this gets a little tricky when the risk category/structure class is something other than II, since the importance factors in TIA are more elaborate (wind speed with no ice, with ice, ice weight) than those in the IBC (who simply provide a number for the wind speed with no ice). We do a lot of work on the Atlantic coastline, and these changes would be most beneficial to our clients. Any interpretation of this would be greatly appreciated.
(341030 views) - Can ASCE 7-16 wind maps be used per TIA-222-G Section 2.6.4.1 to determine the basic wind speeds for a TIA-222-G Tower Design?
(24029 views) - Can section 2.8.2 also be applied to a TIA-222-F structural analysis since currently this code does not include any displacement limits?
(542118 views) - Does section 2.8.2 Limit State Deformations of ANSI/TIA 222-G apply to the tower structures, or does it apply to appurtenances only?
(550787 views) - Does section 2.8.2 Limit State Deformations of ANSI/TIA 222-G apply to the tower structures, or does it apply to appurtenances only? If this displacement limit applies to tower sections, in the case of a stealth monopole tower would the 3% limit be applied over the whole height of the tower (tower+stealth section) or should it be applied over just the stealth section?Can section 2.8.2 also be applied to a TIA-222-F structural analysis since currently this code does not include any displacement limits?Thanks,
(548628 views) - Does TIA-222-G include any consideration of loads other than wind, ice, and seismic? I am looking at a situation in a coastal floodplain which is subject to flooding, with the possibility of impact loads from loose boats. How should these loads be taken into consideration?
(357914 views) - For double angles, are the modified (KL/r)m equations shall be considered along y-y axis only?
(538748 views) - Hello,The effective projected area of transmission lines mounted in a cluster is based on the appropriate out-to-out dimension of the cluster (Fig. 2-12 on Rev. G). In other words, (12) 2" lines stacked 6-on-6 with clear spacing of 1" and Ca= 1.5 will have an (EPA) N = [2x6+5x1)] x 1.5 for ice loading, assuming ice will fill in all spaces. Does this mean, for no ice loading, space between the stacked lines can be neglected? Ex. (EPA) N = [2x6]x1.5, assuming lines are perfectly stacked and ice does not control.RegardsShan
