Abstract:
Tests were conducted to determine the relationship between curvature in a reinforced concrete slab and the behavior under cyfic loading of steel anchors embedded in the slab. Test results showed that the pullout deflection of the grouted bolts and self-drillers varied almost directly with slab curvature. The behavior of the wedge anchors was less well-defined because with each succeeding test performed on a set of wedge bolts the anchors siipped.further down the conical head of the bolt, producing increased resistance to pullout. Further re-search is needed to define better the relationship between anchor performance and level of applied moment.
