This paper presents an experimental study on load-deflection behavior of adhesive, grouted and expansion anchors. The anchors were post installed into a high strength concrete block of dimensions 240×150×40 cm. The concrete block had a compressive strength of 64 MPa at the time of testing. Totally, 41 individual anchors were tested including 21 under static tension, 10 under cyclic tension and 10 under shear loading. After each test load-deflection diagram was drawn and comparisons and evaluations were performed on the basis of failure mode, pullout load, and stiffness of the anchors. The experimental results were also checked against the anchor capasities predicted by ACI 349 design method. Provided the failure of the anchors were of concrete cone type, substantial damage was observed on the test block. For short embedment lengths, ACI 349 method predicted reasonable failure loads but with the increase in anchorage length the prediction becameunconservative.
