NOTE
(1) According to standard EN 523.
(2) The helical or cross-wise hoops mentioned in this table, which resist the bursting forces of concrete in the anchorage zone, are only valid when an anchorage is isolated in a pris-
matic section element (test block) and for concrete with a cylinder strength fcmin of between 23 and 43 MPa.
 When the anchorages are grouped along one line or more, continuous reinforcement of an equivalent section has to be provided, linking all anchorages and correctly anchored
within the structure.
