Embedment plate on concrete wall

Embedment plate on concrete wall

Embedment plate on concrete wall

(OP)
Hello everyone, thanks for your focus.

I am designing a emebedment plate casting in concrete wall with 4 stud, a steel stud will be bolt connected with this embedement plate via another vertical gusset plate, actually this gusset plate is welded with the embedement plate. I have three questions need your instruction.

1. Regarding to design the embedment plate thickness, can I only check the bending of embedment plate cantilevering off the line where gusset plate located? Bending will be accouted by the product of stud tension and its arm.

2. Further to the question 1, if there are two studs with tension on one side of gusset plate, can I design the moment from the closer stud but ignore the farther stud?

3. In designing the stud based on APP D of ACI 318, if straight stud is applied and 12d lenght is preferred (not mentioned development length), how can I deisgn the pullout strength for such straight stud?

Thanks in advance.

RE: Embedment plate on concrete wall

Can you post a sketch?  I'm not quite following how the stud is going to attach to a vertical plate then to the embed plate.

1) A sketch will help us answer this
2) Again a sketch would help
3) You really just need to get familiar with App. D.  There is no straightforward answer.  You'll have a lot a geometric constraints, and you might find (if you have small edge distances) that a deeper embedment will REDUCE your capacity (on paper anyway).
