This is essentially the same. Some of the verbiage and notation appears to
have been clarified, but the intent is still based on a "pull-out" cone
model. The effective area aspect is for groups of anchors spaced closely
together and thereby behaving as a single failure group.
I find section 1923 to be rational and straight forward.
