Using bolts secured by expoxy, you can achieve a strength of 31,000 lbs under tension, or 16,000 lbs of shear force, with a 1.25" diameter bolt installed 18.75" deep in concrete, using Simpson Company's AT (acrylic) expoxy.
Lower tension and shear force loads can be achieved with smaller diameter bolts, installed in shorter holes.
These are comparable to loads sustained by their SSTB embedded foundation bolts.
