ACI/IBC/SBC - Wall Pier Design

Hi all,

I noticed that there are some changes/modifications to the codes that I was not aware of:

1.    ACI [21.9.8] Talks about Wall piers and their design

2.    IBC [1905.1.4] Talks about deleting ACI [21.9.8] and replacing with text per the IBC

3.    SBC deletes IBC[1905.1.4] leaving the original ACI [21.9.8] unchanged.

That is news and FYI (in case you may be late to the party – like me…)

Below is the SBC spec - which deletes the IBC changes to the ACI - leaving the ACI unchanged

	Additionally and interestingly,,, the WAC does weigh in on the Wall pier Design issue. It disregards it and rejects it out of hand. It does not recognize the definition of wall pier nor the treatment of Wall pier design.... Interesting?
