- 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.
Per TIA-222-G Section 2.6.4.1 the wind maps per ASCE 7-10 may be used to determine the basic wind speeds. The ASCE 7-10 wind ... - 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?
The current direction is to publish an Addendum to address the wind map changes in ASCE 7-2010. ...
