Abstract:This paper addresses the load-deflection behavior of adhesive and grouted anchors embedded in both plain and steel fiber-reinforced normal- and high-strength concretes. Both 12 and 16 mm-diameter adhesive anchors were tested at embedment depths ranging from 40 to 160 mm, while grouted anchors of 16 mm diameter were tested at 80, 120, and 160 mm embedment depths. A total of 57 anchors (39 adhesive and 18 grouted anchors) were tested under monotonic tension loading. Test results showed that pullout capacities of the anchors were not significantly affected by the addition of steel fibers into the concrete. The ultimate deflection and toughness, however, were greatly improved provided that the anchor failed through concrete breakout. Current design methods (ACI 349-85 and concrete capacity design [CCD]) overpredicted the pullout capacity as governed by concrete failure. The overprediction increased with increasing concrete strength, but slightly decreased with the addition of steel fibers for a given concrete strength.
