A set of barrels can be used with a mono-strand stressed tendon as an alternative to an anchor block. block See anchor block. bond The adhesion of concrete or grout to prestressing strands, wires or bars, or to unstressed reinforcement, either through friction or mechanical interlock. [1]: 9 bond strength The resistance to separation of ...
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 ...
A dolos (plural: dolosse [1]: 10 ) is a wave-dissipating concrete block used in great numbers as a form of coastal management. It is a type of tetrapod . Weighing up to 8 tonnes (8.8 short tons ), dolosse are used to build revetments for protection against the erosive force of waves from a body of water.
Special wall fasteners (screw wall plug anchors) designed for autoclaved aerated concrete including gypsum board and plaster tiles are available at a higher cost than standard expandable wall plugs, including special safety-relevant anchors for high load bearing; [59] [60] [61] It is recommended that fixing holes be drilled using HSS drill bits ...
Under tension loading, the concrete capacity of a single anchor is calculated assuming an inclination between the failure surface and surface of the concrete member of about 35°. The concrete cone failure load N 0 {\displaystyle N_{0}} of a single anchor in uncracked concrete unaffected by edge influences or overlapping cones of neighboring ...
A wave-dissipating concrete block is a naturally or manually interlocking concrete structure designed and employed to minimize the effects of wave action upon shores and shoreline structures, such as quays and jetties. One of the earliest designs is the Tetrapod, invented in 1950.
In this case, concrete base material might be undamaged. Pull-out: the anchor is pulled out from the drilled hole partially damaging the surrounding concrete. When the concrete is damaged the failure is also indicated as pull-through. Concrete cone: after reaching the load-bearing capacity a cone shape is formed.
