A new type of retrofit anchor bolt that uses deformed reinforcing bars and a commercial adhesive was developed and then an experimental study was carried out to determine the behavior of the anchors in direct shear. The steel-to-concrete interface was tested. Plain concrete slabs with about 20-MPa compressive strength were used for 23 direct shear tests performed. Test variables were anchor diameters (D16, D22, and D29) and edge effect. Three different shear tests were completed: simple shear, edge shear where anchors were pulled against the concrete core, and edge shear where anchors were pushed against the concrete cover. In the simple and the edge shear tests where the anchors were pulled against the core, the theoretical dowel strength determined by f_y/\sqrt{3} was achieved but with relatively large displacements. The shear resistances increased with the increasing displacements. In the edge shear test where the anchors were pushed against the cover, the peak shear strengths significantly lower than the theoretical dowel strength were determined due to cracks developed in concrete when the edge distance was 80 mm. The peak strengths were about 50% of the dowel strength for D16 bar, and about 25% or less of the dowel strength for D22 and D29 bars. Test results revealed that the edge shear where the anchor was pushed against the cover controled.
