Abstract: This paper describes a study of exposed anchors in shear such as those in a typical column footing connection with a grout leveling pad. Two groups of double-shear tests of threaded rods (ASTM A193 Grade B7) were conducted along with finite element analyses to simulate the behaviour of exposed anchors in shear. The study indicated that the exposed length and boundary conditions of exposed anchors significantly affects the load-carrying capacities and the corresponding failure modes because the anchors are subjected to combined bending, shear, and tension. Design equations were proposed for exposed anchors based on the experimental and numerical results.
