The tensile force in the stressing steel is resisted by one of three methods:
Abutment method - an anchor block cast in the ground.

Strut method - the bed is designed to act as a strut without deformation when tensioning forces are applied.

Mould method - tensioning forces are resisted by strong steel moulds.

It is usual in pretensioning factories to locate the abutments of the stressing bed a considerable distance apart so that a number of similar units can be stressed at the same time, end to end using the same tendon. This arrangement is called the "Long Line Process".
