DYWIDAG Post-Tensioning Systemsare world renowned for reliability andperformance, most suitable for allapplications in post-tensioned con-struction. They embrace the wholespectrum from bridge construction,buildings, to civil applications, aboveand underground.

The first ever structure built with a pro-totype DYWIDAG Post-TensioningSystem using Bars was the arch-bridge

Alsleben (Germany) in 1927. From thattime on DYWIDAG has continuouslyimproved its systems to keep up withthe growing demand of modern con-struction technology. In addition to thetraditional post-tensioning system usingbars, that is mainly geared towardsgeotechnical applications, buildingrehabilitation and strengthening, DSI

offers a complete product line in strandpost-tensioning (bonded, unbondedand external) as well as stay-cablesbeing able to fully serve the post-ten-sioning construction. DYWIDAG Post-Tensioning Systems have always com-bined highest safety and reliability stan-dards with most economical efficiencyin their research and development.Dependable corrosion protection meth-ods of the DYWIDAG Post-TensioningSystems contribute to the longevity ofmodern construction. High fatigueresistance is achieved with optimizedmaterial selection and cautious detail-ing of all the components especially intheir system assembly.

We look back on many years of valu-able experience in the field of post-ten-sioning which leads to our extremelyversatile product range that offers eco-nomical solutions for practically any

problem. This includes our highly devel-oped, most sophisticated equipmentwhich is easy to operate in all phasesbeginning with assembly, installation,stressing and finally grouting.

Standard Strands

Strands are made from 7 individualcold-drawn wires, 6 helically woundouter wires and one center wire (kingwire). The mechanical properties of thestrand as well as corrosion protectionproperties are most important to DSI.Strands can be supplied either bare,galvanized or epoxy-coated withoutany loss in strength including thewedge anchorage. For a maximum incorrosion protection we offer electrical-ly isolated systems using polyethylene(PE) or polypropylene (PP) ducts. Seealso page 6.

Corrugated Duct

Metal ducts represent the mosteconomical means to create a void fortensile elements. These thin-walled(0.25 - 0.35 mm), ribbed sheet metalducts provide a fair secondarycorrosion protection with excellentbond behavior between tendon andconcrete. Primary corrosion protectionis provided by the alkalinity of groutand concrete.

Thick-walled polyethylene/ polypropylene (PE/PP) plastic ducts provide lonterm secondary corrosion protectionespecially in aggressive environmentssuch as waste water treatment plantsacid tanks or silos. Plastic ducts are aintegral part in the electrically isolatedtendons.

The minute friction coefficients forstrands inside PE duct enhance thefatigue life of tendons. Plastic ductselectrically isolate the tendon from thstructure and thus provide a tool toinspect the integrity of the corrosionprotection system.

Multiplane Anchorage MA

The two-part multiplane anchorage isprimarily used for longitudinal tendonsin beams and bridges.

The wedge plate and the conicalanchor body with usually three loadtransfer planes introduces the pre-stressing force continuously into themember with minimal front area.

The separation of anchor body andwedge plate makes it possible to insertthe strand after casting the concrete.The wedge plate self-centers on theanchor body providing consistentassembly and installation as well astrouble- free stressing.

Plate Anchorage SD

The single unit plate anchorage isdesigned for plate structures as well astransverse tendons in bridges. Smalledge and center distances allow for aneconomical anchorage layout in con-densed situations. The Plate AnchorageSDR has an enlarged plate that isdesigned to work with lower actualstrength concrete.

Mono Anchorage EV

Bond Head Anchorage ZF/ZR

Primarily used with prefabricated ten-dons, it is also possible to fabricate thisanchorage on site. The strand wires areplastically deformed to ensure a safeload transfer up to ultimate capacity inthe area of the bond head proven instatic as well as in dynamic applica-tions. Depending on the boundary con-ditions either two-dimensional or athree-dimensional bond head anchor-age pattern is available.

Coupler M/ME (Floating Anchorage Block)

Cylindrical structures (water tanks,digestor tanks, large pipes or domeshells) that require circumferential post-tensioning are the principal applicationsfor the non-fixed coupler M/ME. Thetendon anchorage consists of ananchorage block with wedge holes onboth sides to accept bare or greasedand sheathed strands. The strandsactually overlap in the block and usethe belt-buckle principle. The ring-ten-don is very compact and requires avery small pocket only.

Installation

DYWIDAG-Systems International hasdeveloped three different methods toinsert strands into ducts. The selectionof the insertion method depends on theboundary conditions of the structureand the job site.

Method 1: Pushing

To push strands into the duct on thejob site is very economical and can bedone either before or after casting theconcrete. The pushing equipment can

be installed remotely and connectedflexibly to the insertion point. DSIstrand pushers provide relatively highspeed of up to 8 m/s and require mini-mal operating personnel of only twomen. These advantages make thismethod the preferred standard forstrand installation.

pushing device

tube

Method 2: Pulling

To install strands while pulling them intothe duct can be very efficient in specialstructures, for example where the loopanchorage is used. In normal cases thewhole bundle of strands is pulledthrough winching with a steel cable.

Method 3: Pre-Assembled Tendons

The prefabrication of tendons either inthe shop or in the field can also be veryeconomical, especially with shorter ten-dons and short shipping distances.Special uncoilers or hydraulic winchesare necessary to properly install thetendons in the structure.

Stressing

DYWIDAG has developed a series ofjacks and rams and hydraulic pumps inorder to reach the target stressing load.The necessary versatility is provided bychanging devices that make one unitadaptable for many different tendonsizes. DYWIDAG Equipment isdesigned to cover a wide spectrum ofapplications with jack capacities rang-ing from 250 kN up to 15,000 kN.

DYWIDAG Rams are highly sophisti-cated, but still convenient to operate.They employ inner tube bundles withautomatic gripping devices that guidethe strand safely through the inside ofthe ram. This feature allows thestressing operation to be controlledwith the highest degree of reliability aswell as minimal wedge seating lossesby benefiting from the power seating

option. Power seating is a way ofhydraulically pressing in the wedgeswith a predefined load individually andsimultaneously rather than relyingsimply on friction seating. DYWIDAGRams also make it possible tooverstress and release the tendon tocompensate for friction losses andmaximize the stress level over thetendon length.

Every ram has a pressure relief valve forsafety reasons that activates to limithydraulic pressure should the hydraulicpump malfunction. To further verify thestressing operation an additional gaugeport is provided directly on the ram.

Stressed tendons can be destressedwith special wedges and a special ramconfiguration.Hydraulic pumps can be equipped witha convenient remote control device.Further information concerning theequipment is provided on page 25 andfollowing.

Grouting

The durability of post-tensioned con-struction depends mainly on the suc-cess of the grouting operation.The hardened cement grout provides abond between concrete and tendon aswell as primary long-term corrosionprotection for the prestressing steel.

DYWIDAG has developed a groutingoperation that is based on thixotropicand highly plasticized grout, and utilizesdurable grouting equipment. Advancedmethods such as pressure grouting,post-grouting and vacuum grouting areall results of many years of develop-ment.

Grouting is always done from a low-point of the tendon. This can be one ofthe anchorages where a grout cap withgrout hose is the port for the grout or

along the tendon utilizing an intermedi-ate grout saddle. All grouting compo-nents are threaded for easy, fast andpositive connection (see page 26 andfollowing).

Calculation of Elongation

The stressing records are part of thestructural design and serve as a basisfor the stressing operation. Besides theprestressing data, they contain thesequence of stressing and directions

for procedures directly connected witthe stressing operation, such as loweing of the formwork and releasing ofbearings.

Calculation of Strand Tendon Elongation
