RE: FW: CMU Site Wall using 2001CBC -- Warning: Comical Aside

Jon,
First of all it is Harold.
Secondly, I admit that every now and then it is fun to tug on someone's leg.

Humor pre re na'ta.  (Hint it is Latin)

All seriousness aside,
Harold Sprague

Howard,
Was that covered in "Zum Trag- und
Verschiebungsverhalten von Kopfbolzen bei zentrischem Zug"?  Or
do we need to order something like "Zu den Verhaeltnissen unter
Statikerberechnungstexten der vereinigten Staaten"?
:)
