Hi,

            Is anyone able to provide me with a sample calc for anchoring a brace frame base plate to concrete.  The uplift load I have is 335 kips. I have worked on it but the size I obtain for the grade beam size to resist the uplift load in breakout seems quite high.  I have to use a 6'6" grade beam and embed the anchors at least 60 inches in order to get it to work.   Any feedback would be great.   Thank you.
