Masonry crushing
Masonry crushing
(OP)
Is the only way to combat masonry crushing per ACI 530-11 equation 2-7 by increasing the diameter of your bolt? Can you justify excluding this failure mode in some way? I'm just trying to figure out how you get any decent capacity out of an anchor bolt in masonry when you have to check this code provision.

Meanwhile, a piece of southern pine is 565 psi. Go figure.
The TEK manual has some charts for anchor bolts. You may need to used high strength grout or bigger / more bolts.
