DYWIDAG Bonded Post-Tensioning Systems Using Strands

DSI Multiplane Anchorage MA

Multiplane Anchorage MA


  • Two-part anchorage, especially suitable for longitudinal tensioning of beams and bridges
  • Continuous introduction of prestressing force into the member thanks to an interaction of the wedge plate and the multiplane anchor body
  • Subsequent insertion of strands is facilitated by the separation of anchor body and wedge plate
  • Safe installation and problem-free tensioning thanks to optimized centering of both anchor parts and the hydraulic jack
DSI Coupler R

Coupler R


  • Fixed coupler that is used at the joints of construction segments and that allows the user-defined lengthening of MA Multiplane Anchorage Tendons.
  • Tendon Coupler R is also used as live end tensioning anchor
  • Easy and safe installation of individual strands in the coupled tendon
DSI Coupler D

Coupler D


  • Movable coupler that can be located almost anywhere in the structure and allows the individual lengthening of MA Multiplane Anchorage tendons.
  • Utilization is independent of joints
  • Coupler D can be used in small construction cross-sections
  • Easy and safe installation of individual strands through individual strand sockets
DSI Plate Anchorage SD/ Rib Plate Anchorage SDR

Plate Anchorage SD/ Rib Plate Anchorage SDR


  • Single unit anchorage, primarily used for post-tensioning plate-like structures and for transverse post-tensioning of bridges
  • Small edge and center distances allow for an economical anchorage layout and extremely thin plate dimensions.
  • Rib Plate Anchorage SDR with extended plate can be used as an alternative to type SD even with relatively low concrete strengths.
DSI Bond Head Anchorage ZF/ZR

Bond Head Anchorage ZF/ZR


  • This anchorage is a bonded anchorage and is often used with prefabricated tendons
  • The Bond Head Anchorage can also be fabricated directly inside the structure
  • Special deformations of the strand wires in the head assure safe load transfer in static as well as in dynamic applications
  • Both flat and rectangular bond head patterns are possible
DSI Loop Anchorage HV

Loop Anchorage HV


  • Utilized in plate-shaped and wall-shaped structures (off-shore structures, LNG tanks, etc.)
  • The 180° loop is positioned in the center of the tendon
  • Simultaneous stressing at both ends
