Abstract:
Presents a brief review of current design methodology for calculating tensile and shear capacities of steel anchors in concrete. A practical approach to the consideration of tensile capacity of multiple anchors with overlapping shear cones is presented. A method for calculating tensile capacity when anchors of different sizes are used is also presented. Equations are presented to predict shear capacity of both cast-in-place and expansion anchors when the shear force resisted by the anchors is directed toward a free edge. The validity of these prediction equations is documented by plotting the predicted capacities versus capacities obtained in tests for various anchor sizes and concrete strengths.
