Headed Studs in Tension
Headed Studs in Tension
(OP)
I have a project that has a couple of headed studs on a baseplate for a guard attachment. They are in proximity to eachother (4"). Does anyone have a spreadsheet that can be used to determine the tensile capacity. Or point me to something I can quickly use. Alternatively if someone can point me to a paper that addresses this. I've done an internet search and am saturated with the amount on non-useful information.
thanks Dik

- AISC 360-16, Section I8.3b, (p. 16.1-109): Tensile Strength of Steel Headed Stud Anchors in Composite Components
- ACI 318-14, Section 17.5.1.2(a) (p. 247): For cast-in headed stud anchor
I believe that using either code will result in the same capacity in this case.RE: Headed Studs in Tension

Ok, then what I stated above is an incomplete answer. I recently spent a lot of time writing a piece of software for concrete anchorage design. As you're probably aware, the basic requirements are spelled out in ACI 318, Chapter 17 (which I found parts of to be borderline incomprehensible).
The reference PCA - "Notes on ACI 318-11" has some decent design examples in Chapter 34 which helped me a lot. In particular, for your problem, I think Example 34.2 (p. 34-38) will be helpful. It's for a group of headed studs in tension.
Chapter 34 also contains several tables with design capacities for single anchors in tension and shear.
I found Hilti Profis software as well as the similar program by Simpson Strong-Tie to be very useful as well. My opinion is that the complexity of the ACI code has made it nearly impossible to do this stuff by hand for anything but the simplest cases.

If you need it, you can increase your breakout capacity of your tension anchor by using the compression strut to restrain it. There have been studies on it and there's a capacity increase factor you can apply based on it. If you need that extra bump I can look for it.

Thanks... there are a bunch (binary term for PC) of others on this site that I hold in high regard.

You can add the loading as a moment if that is the case as well if you require.
