Bonded Strand Post-Tensioning System

Anchorage Types

Multiplane Anchorage MA

Multiplane Anchorage MA

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

The wedge plate and the multiplane anchor body with usually three load transfer planes introduce the pre-stressing force continuously into the member with minimal front area. The MA anchorage can be installed with and without helix reinforcement.

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.

Plate Anchorage SD

DSI Plate Anchorage SD

The single unit plate anchorage is designed for plate structures as well as transverse tendons in bridges. Small edge and center distances allow for an economical anchorage layout in condensed situations.

Plate Anchorage Type ED

DSI Plate Anchorage Type ED

The two-part plate anchorage can be used in slabs and similar structures, e.g. transversal prestressing in bridge decks. The wedge plate self-centers on the anchor plate providing consistent assembly and installation as well as trouble-free stressing.

Loop Anchorage HV

DSI Loop Anchorage HV

Often used in large plate-shaped structures, walls in off-shore structures or LNG tanks with generally static loadings. The 180º loop should be positioned in the center of the tendon to allow for non-slippage during simultaneous two-end stressing.

Bond Head Anchorage HL/HR

DSI Bond Head Anchorage HL/HR

Primarily used with prefabricated tendons, it is also possible to fabricate this anchorage on site. The strand wires are plastically deformed to ensure a safe load transfer up to ultimate capacity in the area of the bond head proven in static as well as in dynamic applications. Depending on the boundary conditions, either a rather flat or a bulky bond head anchorage pattern is available.

Flat Multiplane Anchorage FMA

DSI Flat Multiplane Anchorage FMA

The Flat Multiplane Anchorage of max. 5-0.62" strands in one plane to deviate into one oval duct is designed to be installed in thin members such as transverse post-tensioning of the top slab of box-girder bridges and prestressed flat slabs.
