F/n = 23 kN per anchor during initial lift (n = 2 lifting anchors) Transport loads in the yard and on-site Suction due to casting bed adhesion is not considered, as the calculation takes into account the lifting device dynamic coefficient. S = (W x Ksl x Kd) / n = (64.8 x 1.16 x 1.2) / 2 = 45.1 kN load resistance required per anchor
Single helix earth anchors Guyed mast anchor. An earth anchor is a device designed to support structures, most commonly used in geotechnical and construction applications. Also known as a ground anchor, percussion driven earth anchor or mechanical anchor, it may be impact driven into the ground or run in spirally, depending on its design and intended force-resistance characteristics.
Concrete cone failure. Concrete Cone Model [ 1] Concrete cone is one of the failure modes of anchors in concrete, loaded by a tensile force. The failure is governed by crack growth in concrete, which forms a typical cone shape having the anchor's axis as revolution axis .

The derivation of the maximum arching moment of resistance of laterally restrained concrete bridge deck slabs utilised Rankin's idealised elastic-plastic stress-strain criterion for concrete, valid for concrete cylinder strengths up to at least 70N/mm 2, which he had derived on the basis of Hognestad, Hanson and McHenry's ultimate parabolic ...

An anchor is a device, normally made of metal, used to secure a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin ancora, which itself comes from the Greek ἄγκυρα ( ankȳra ). [ 2][ 3] Anchors can either be temporary or permanent.
