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.
