When selecting an anchor, consider the element formwork and the ease of placement and securing of the anchor prior and during the pouring of the concrete. For example, some of the anchors shown in figures 4-6, can be placed into thin wall elements as the anchor chair maintains the position relative to the element thickness.
Helical anchors consist of an extendable steel shaft with helical bearing plates. Piles or piers refer to strong base elements that withstand or transfer vertical/horizontal loads. Anchors are piles utilised only in tension applications like restraining wall tiebacks or vertical ground anchors made to resist overturning forces.
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.
The magnitude of total anchor force required in the tieback can be determined by analyzing the soil and groundwater properties as well as sources of external loads applied to the system. [ 2 ] The bond length of the tieback must extend beyond the potential critical failure surface of the soil.
Individual strand tendons placed directly into the concreted structure (e.g., buildings, ground slabs) Bundled strands, individually greased-and-sheathed, forming a single tendon within an encapsulating duct that is placed either within or adjacent to the concrete (e.g., restressable anchors, external post-tensioning)
The tension failure loads predicted by the CCD method fits experimental results over a wide range of embedment depth (e.g. 100 – 600 mm). [2] Anchor load bearing capacity provided by ACI 349 does not consider size effect, thus an underestimated value for the load-carrying capacity is obtained for large embedment depths.
