TIA-222-H 1

[ENGINEER92]

The tower code was updated this year to TIA-222-H (Rev H). On the front of TIA-222-H it says "Effective January 01, 2018". Rev H was mainly updated to match the changes for IBC 2016. If the state I am working in hasn't adopted the IBC 2016 and still is under the IBC 2012, could I use Rev H or do I have to wait until the state adopts the IBC 2016?

I apologize I meant IBC 2018. (I was thinking ASCE 7-16)

When I worked on towers (2014?) some jurisdictions adopted IBC versions used TIA G, and some used TIA F. We always used whatever TIA version the jurisdictions adopted IBC version dictated, meaning in your case we would use TIA G.

I believe some other companies might have done it differently, but that was our standard practice.

I worked under G a few years back too, and I remember there was a code provision in the IBC deferring to TIA 222 for the tower design. Don't know if that is still there though...I would have to look.

I would like to use TIA H, since it will eventually be adopted, and get use to using it. Section 3108.1 of IBC 2016 does state "Towers shall be designed and constructed in accordance with provisions of TIA-222." That makes me think I can use the latest TIA-222 (TIA H). I do have a pause for concern and that is that the TIA H adopted the wind speed and ice thickness maps in the ASCE 7-16. And the Wind speed and ice thicknesses has gone down in my areas.

Apologize again, "Section 3108.1 of IBC 2012"
