Design of Anchor Reinforcement in Concrete Pedestals

the concrete with the anchors are used for transferring tension force only. For large shear forces, where the shear friction is insufficient, shear lugs or anchors can be used to transfer the load. The shear forces must be transferred to concrete pedestal. Strut-and-tie models can be used to analyze shear transfer to concrete pedestal. 4.1.

The connection of a cable to its supports acts as a pin joint (hinge), with the result that the reaction (R) must be exactly equal and opposite to the tension in the cable (T). The R can be resolved into the vertical and

Prestressed concrete - Wikipedia

Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service.: 3–5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service.
