Abstract:The use of channel anchors in concrete building construction is relatively new. The shear capacity of single stud anchors can be reasonably predicted using the concrete failure cone method or empirical formulas, but a similar shear capacity prediction relationship has not been clearly developed for channel anchors. A shear capacity prediction method was developed, and a relationship is proposed based on a modified concrete failure cone concept. This modified cone method recognizes the intersection of the failure cone with a free edge or edges. Predicted shear capacities of channel anchors obtained from the proposed relationship were compared to test results. The prediction percentage errors ranged from 18.8 under-prediction to 21.6 over-prediction, with a total average error of 8.96 percent. This paper contains tabular results and figures supporting the proposed method of evaluating the shear capacity of channel anchors.
