Principle / Scope of application:
. The external residue creates a back stress that is partially or fully balanced with the stress due to self and service loads. Thereby helping to increase the bearing capacity of the cross-section
. Used for a variety of structures: concrete, steel, wood ……temporary structure, permanent structure.
Advantage:
Especially effective with structures: PT structure, round tank, silo, continuous structure
Disadvantages:
The anchor system must ensure a long service life
It is necessary to ensure anti-fire and anti-corrosion measures for PT cables
