Abstract

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 uncracked, 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 ACT 349-90 and concrete capacity design (CCD) methods. Based on the results of the experiments, the constant 0.54 in the steel strength equation of a wedge anchor was determined from test data at 5%R fracture probability. In terms of the CCD method, a normalization coefficient of 0.61 is appropriate for single near-edge anchors loaded in shear.
