Cracks and damage occurring in concrete members as a result of earthquake-induced ground motion may impact the performance of anchors installed in those members. To investigate this issue, an earlier experimental study examined the response of tension-loaded anchors installed in a slender full-scale reinforced concrete shear wall subjected to cyclic loading. The present effort extends that investigation to anchors installed in full-scale low-aspect-ratio concrete shear walls. The test walls, described in a companion paper, were detailed with minimum horizontal reinforcement to ensure a range of crack types with appreciable distribution throughout the wall. The load and displacement histories of the anchors are analyzed to characterize their performance under a variety of concrete damage states. The anchor axial strength reduction is estimated at key performance limit states typical of concrete shear walls to provide a link between structural performance and anchor response. Finally, the residual tension capacity of the anchors is assessed in contrast with the concrete damage distribution in the wall.
