Steel cantilever connected to concrete slab: combining bolts in shear with concrete in compression 1

[brTCP]

Hi,
due to the limited space, I often find myself wondering whether I could use bolts in shear (bolts 1 in the figure) in conjunction with concrete in compression (perhaps with bolts no. 2 to hold the shear force). In these cases, I find it hard to find the forces in the bolts with confidence. What model do you use to calculate the bolt/anchor forces in these cases? Can I assume a linear strain profile as in reinforced concrete? I look forward to your opinions.

Follow the stiffness and slip - there is likely no way there will be any significant force that can develop in the bolts at position 2 before the compression side has broken away. most holes for bolts are 1/16" larger so the vertical leg must stretch at least half of that before engaging the bolt at all.

For the loading you have applied the angle will try to move down and rotate on the wall. it is restrained by a compressive force below anchor 2, and a shear in anchor 1 for the moment, plus compression in the horizontal leg for the axial load. I still see that action as anchor 2 not really adding anything to the capacity of this connection.
