This study concerns the prediction of shear capacity, as governed by concrete breakout failure, concrete pryout failure, and steel failure, and of single anchors located close to free edge and located far from a free edge and installed in untracked, unreinforced concrete. For this purpose, the methods to evaluate the shear capacity of the single anchors in concrete are summarized, and the experimental data are compared with shear strengths using the two current methods: the ACI 349-90 and concrete capacity design methods. Based on the results of the experiments, the constant 0.568 in the steel strength equation of a wedge anchor was determined from test data at 5% fractile probability. In terms of the CCD method, a normalization coefficient of 0.659 is appropriate for single near-edge anchors loaded in shear.
