Anchor Bolt Tension in BP subject to Moment
Anchor Bolt Tension in BP subject to Moment
(OP)
Can someone point me to a sample calc for determining the tension force in an anchor bolt for a base plate subject to overturning forces? I need to determine if an as-built arrangement of four 1/2" diameter anchor bolts is adequate. I already did a quick check using a simple couple to determine the tesion in the bolts and they appear inadequate; I would like to do a more rigorous analysis (moving neutral axis) but don't have any reference material in my current office. I seem to remember my old Gaylord and Gaylord Steel Design text having a simplified method.
Anyone...anyone...Bueller...?
Thanks
Ron

I believe that is what he already did with his "simple couple" analysis.
RRBegin-
I would refer to you AISC Design Guide # 1. A new version just came out, but even if you have the older version it should give you what you are looking for. The main difference between the new and old one is that the new looks at rectangular compression block rather than the more traditional triangular compressive stress diagram. The new one is also more suited to LRFD.

I will dig through my reference material in my attic when I return home and pull out some of my old stuff.

PackerFan-can you send me your post directly? I work for a federal agency and they have blocked the url where your sample is posted.
The address is RONunderscoreBEGINatFWSdotGOV

My ACI 318-05 clearly states in D.2.2 on page 381 - "....Specialty inserts, through bolts, multiple anchors connected to a single steel plate at teh embedded end of the anchors, ADHESIVE OR GROUTED ANCHORS, and direct anchors such as powder or pneumatic actuated nails or bolts, are not included......"
Does anyone see this including Hilti or Powers adhesive anchors in appendix D?

Have a look at this site for your bolted connection problem
with a moment applied.
I cannot open your calcs so I can't comment on those.
