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 f

cmin

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.

(4) (complying with standard) EN 523.
