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 f
cmin
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.
