Steel anchor bolt embedment in concrete problem
Steel anchor bolt embedment in concrete problem
(OP)
I have a steel beam column that I'm needing to anchor into a concrete pier. Using Appendix D via the "Simpson Anchor Designer for ACI 318" program I'm not getting anything to work. I have a moment of 198ft-k and shear forces of 16.5k. My breakout strength is the controlling factor. I have nearly 90 kips of tensile force on my anchors in an overturning moment situation so I'm using (3) 1-3/8" anchors per side. Due to space restrictions, I can't make my steel base plate or concrete base any bigger. What options do I have for my six anchor-in-base-plate scenario? Surely there has to be something I could do....and I'm just not thinking of it. Any thoughts would be appreciated.

The issue is tension, and you guys and that paper have been helpful.
I did notice today when I opened up the Simpson program that there was an update available, and it WAS more friendly to designing with anchor bolts, but it couldn't solve my problem. I'll revert to a spreadsheet or hand calcs.
Thanks again.

Maybe you could just post some screenshots. I have been contemplating creating a worksheet for a while now. Does your program do irregular conrete geometries? (Round piers, etc?)
Also, did you include the calculation of developments, etc if the Appendix D checks fail?

It doesn't do development calcs for rebar, it's strictly for App. D. I've gone through some of the development calcs already, and that's pretty easy, straightforward, and quick. It would also add another dimension of complexity to the sheet.
