The anchor selection, together with additional reinforcement, and rigging arrangements is influenced by: - The dead weight of the element - The number of anchors in the element and the configuration of the anchor - Capacity of the anchor at the specific concrete compressive strengths at time of lift - The dynamic loads applied during lifting ...
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.
The test hammer hits the concrete at a defined energy. Its rebound is dependent on the hardness of the concrete and is measured by the test equipment. By reference to a conversion chart, the rebound value can be used to determine the concrete's compressive strength. When conducting the test, the hammer should be held at right angles to the ...
Moreover, their position must also be coordinated with the reinforcement layout. [3] Different types of cast-in-place anchors might be distinguished: [3] Lifting inserts: used for lifting operations of plain or prestressed RC beams. The insert can be a threaded rod. See also bolt (climbing). Anchor channels: used in precast concrete connections ...
Pre-tensioned concrete is a variant of prestressed concrete where the tendons are tensioned prior to the concrete being cast. [1]: 25 The concrete bonds to the tendons as it cures, following which the end-anchoring of the tendons is released, and the tendon tension forces are transferred to the concrete as compression by static friction.
[1]: 3–4 [3]: 30 anchor block A rigid, usually circular, component placed over a bundle of prestressing strands at the end of a tendon, and that transfers the strand forces directly to the anchor component via tapered wedges located within its internal conical recess.
