AISC Design Guide 1
AISC Design Guide 1
(OP)
I'm using AISC Design Guide 1 - in my situation I have a horizontal cantilever tube imparting the moment on the plate. There is no axial force P, plate dimensions N=11", B=11". Following the examples, I used e=M/P which goes to infinity, so e>e-crit so I have a large moment case.
Going through the numbers I get a plate thickness of 1.5". I thought it was high, so I then checked my answer using Tedds, which puts the eccentricity e = N = 11", which totally changes the required plate thickness to 5/8".
It's been a long day reading the Design Guide over and over, and I can't find a clue as to why Tedds would put e = N. I must be missing something with the statics - obviously M can't = P*e, because P = 0, M would be 0, which is not the case.
Any insight would be appreciated. Thanks.
Thanks.

tension "T" in the anchor rod is approx. given by T = M / [(5/6) * d]
The term 5/6 is to account for the lever arm between c.g. of tension and compression.
