Concrete Lifting Anchors Strength Limit States

AS3850 requires that the strength of the anchor exceeds 2 5 X WLL of the anchor The bar forms part of the anchor itself and therefore its strength must meet this requirement for all its strength limit states NB the limit state strength of the bar may not be limited by its tensile strength only The bar strength is normally limited by shear
