AS 1684 allows for the use of proprietary masonry anchors for fixing bottom plates to concrete slabs. These fixings may be required for resisting the uplift forces at the end of bracing walls and/or the tie-downs of walls due to wind uplift. Tie-down capacity is the lesser of the fixing into the slab and the bearing strength of the bolt and washer in the bottom plate.
