Multiplane Anchorage MA

The two-part multiplane anchorage is primarily used for longitudinal tendons in beams and bridges .

The wedge plate with the conical anchor body and usually three load transfer planes introduces the prestressing force continuouslyinto the member with minimal front area .

The separation of anchor body and wedge plate makes it possible to insert the strand after casting the concrete .

The wedge plate self centers on the anchor body providing consistent assembly and installation as well as trouble free stressing .

he values for the anchorage are based on FIP concrete strength after 28 days of 25N/mm▓ (cube) or 21 N/mm▓ (cylinder)
possible to apply to other code systems or concrete strengths.(e.g. ASTM, BS,DIN and concrete strengths of 35N/mm▓, 45
N/mm▓ )

Max. prestressing load 75% of ultimate load (GUTS) (short term overstressing to 80% is permissible)
