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/mm² (cube) or
21 N/mm² (cylinder)
possible to apply to other code systems or concrete strengths.(e.g. ASTM, BS,DIN
and concrete strengths of 35N/mm², 45
N/mm² )
Max. prestressing load 75% of ultimate load (GUTS) (short term overstressing to
80% is permissible) |
