NOTE
(1) The theoretical quantities must be increased by 10 to 40 % depending on the number of grouting phases.
(2) The helical or cross-wise bursting reinforcing bars given in the table, which oppose the bursting force in the concrete of the anchorage zone, are only valid for an isolated anchorage
in a prismatic section piece (test block), for concrete with a strength fcmin between 23 and 43 MPa (cylinder strength).
When the anchorages are grouped into one of several lines, continuous reinforcement with an equivalent cross-sectional area must be provided to link all the anchorages, appropriately
anchored within the structure.
(3) All the jacks given in the table correspond to optimal use.
