We made trial products, they've parameter of the concrete strength and the edge distance mainly, on base concrete to each of anchor bolts (13φ-56φ) embedded in concrete. We made an experiment that the each of trial products received shearing force action. Consequentely we supposed two empirical equation. One is the equation on maximam shear strength of anchor bolts and the other is the equation on minimum edge distance of base concrete, when anchor bolts are filled with shear resistance. We'll report on the result.
