<strong>JORDAHL</strong> ® <strong>Anchor</strong> <strong>Channels</strong>Quality since 1907<strong>JORDAHL</strong> ® anchor channels are manufacturedby Deutsche Kahneisen GmbH in Germany. Thehis<strong>to</strong>ry of connecting steel <strong>to</strong> concrete begins in1907 with an invention of Julius Kahn, memberof a Chicago family of architects, whose “Kahnirons” opened up completely new possibilitiesfor construction with reinforced concrete. In 1913Anders Jordahl, a Norwegian engineer, who introducedKahn’s reinforcing technology in Germany,developed the <strong>Anchor</strong> Channel by designing aC-shaped profile which was used as reinforcementand connection device at the same time.Today, with a century of experience in anchoringand connection technology “Deutsche KahneisenGmbH” with its brand name <strong>JORDAHL</strong> ® has developedin<strong>to</strong> an internationally renowned companyand a leader of research in anchoring technology,with a strong relationship <strong>to</strong> its cus<strong>to</strong>mers.<strong>JORDAHL</strong> ® ProductsQuality made in Germany since 1907 and usedin projects around the worldState of the art and help cus<strong>to</strong>mers buildefficiently <strong>to</strong> maintain quality standardsMade under strict quality control according <strong>to</strong>German and European approval requirementsEurocode compatible design & approved safetyconcept – <strong>ETA</strong>-09/0338 et al.Comprehensive range of superior anchoringand connection products with accessoriesISO 9001 based internal QA / QC processesWhichever type of construction is in progress,<strong>JORDAHL</strong> ® provides fully developed solutions ininstallation technology: for joining components<strong>to</strong> one another, for suspending loads or forconnecting devices.

Product Range<strong>JORDAHL</strong> ® offers a broad range of products:JTA, the standard anchor channel product groupfor tension, angled tension and shear load.JXA, the <strong>to</strong>othed channels accommodating loadsin all directions.JGB, the anchor channels with welded rebar forinstallation in thin slabs.<strong>JORDAHL</strong> ® T-bolts, available as hammer head,hook head and <strong>to</strong>othed bolts.JTB, the easy solution for corrugated metal sidingand roof installation on concrete.JRA, the anchor channel with parallel weldedrebar anchors for extremly high dynamic loads.W-ProfilesTraditionally <strong>JORDAHL</strong> ® profiles are hot rolledfrom a billet. Therefore they are particularly freeof residual stresses. The geometry is optimized,well-suited for dynamic loads and high clampingforces from the T-bolts. <strong>Anchor</strong> channels madefrom hot rolled profiles are the preferred solutionfor curtain walls under high wind loads, eleva<strong>to</strong>rs,heavy pipes under pre-stressed post-tensionedbridges, etc.K-ProfilesThe smaller <strong>JORDAHL</strong> ® profiles are cold formed in arolling mill which ensures dimensional consistencythroughout the cross sectional area. Cold formedanchor channels can be used for connecting precastelements, taking the dead weight of facadesor for attaching corrugated metal siding.SafetyworkTimeefficiencyLowcostSteel gradesMost profiles are made from carbon steel materialconforming <strong>to</strong> EN 10025 with a minimum yieldstrength of 235 N / mm 2 . Stainless steel grade A4conforming <strong>to</strong> EN 10088 is available upon request.Round <strong>Anchor</strong>sUnless cus<strong>to</strong>m design is required, anchors aregenerally cold-headed in a fully au<strong>to</strong>ma ted andmoni<strong>to</strong>red production process.Simple <strong>to</strong>installNo risk offire<strong>Guide</strong> <strong>to</strong> <strong>ETA</strong> compatible Design5
<strong>JORDAHL</strong> ® <strong>Anchor</strong> <strong>Channels</strong>Curtain WallModern facade systems provide protection foroccupants of office and apartment buildings, aswell as the means for architects <strong>to</strong> create attractivebuildings on the metropolitan skyline.

<strong>JORDAHL</strong> ® <strong>Anchor</strong> <strong>Channels</strong>Prestressed Bolted Jointsand Tightening TorquePrestressing Forces of T-BoltsIn connection technology, for the applicationsSuspended direct and stand-off installationStress in the channel longitudinal directionit is important <strong>to</strong> prestress the bolted connectionsin order <strong>to</strong> prevent undesired loosening or slippageof the bolted connections. Higher-strength bolts(8.8) are not absolutely necessary for this purpose.Grade 4.6 and A4-50 bolts are also adequate if thefollowing points are taking in<strong>to</strong> consideration:In the short term, a force arising from prestressingwith tightening <strong>to</strong>rque is normally higherthan the external load.The applied prestressing force is dissipateddown <strong>to</strong> about 30 % by relaxation.Bolts made of stainless steel exhibit higherfriction than zincplated or HDG bolts. Therefore,stainless steel bolts produce lower prestressingforces.<strong>JORDAHL</strong> ® bolts are supplied ready for installation.They should not be additionally oiled ortreated with lubricants before the tightening<strong>to</strong>rque is applied.The bolted joint may be prestressed only whenthere is steel <strong>to</strong> steel contact.If the channel is set back behind the concretesurface, then the connection must be shimmed bymeans of a suitable washer (see page 34).If this is not followed and the attached part isprestressed against the concrete surface, it leads<strong>to</strong> residual stresses in the component. These cancause cracks or splitting of the concrete component.Suspended Direct and Stand-Off InstallationFor these applications, cold formed and hot rolledprofiles can be used. In order <strong>to</strong> prestress a boltedjoint with electro-galvanized (gv) bolts or stainlesssteel bolts, we recommend <strong>to</strong> use the tightening<strong>to</strong>rques according <strong>to</strong> page 38.T instT instPrestressingforceExternal force =characteristictensile loadExternal force =characteristictensile loadHot rolled profile, hook headbolt and washer ensureuniformly distributed surfacepressure and allow high<strong>to</strong>rque moments.38<strong>Guide</strong> <strong>to</strong> <strong>ETA</strong> compatible Design
The relationship between prestressing force andtightening <strong>to</strong>rque can be seen from the graphsbelow. The prestressing forces vary strongly withthe friction in the thread between the nut and thebolt. Low friction causes high pre-load, typical forhot-dip galvanized bolts with lubricated nuts.Friction is increased for clean galvanized (medium)and stainless steel (high) nuts and bolts. The recommendedinstallation <strong>to</strong>rque may be increasedby 30 % without danger of reaching the yieldstrength of the bolts.Relationship between Prestressing Force andInstallation Torque for:Mild Steel Bolts Grade 4.6 and Stainless Steel Bolts Grade A4-50Prestressing Force [kN]60.050.040.030.020.010.0M 12M 16FrictionmediumlowhighM 20Profile TypeW 72/48W 55/42W 53/34W 50/30W 40/220.00.0 25.0 50.0 75.0 100.0 125.0 150.0 175.0 200.0T inst [Nm]Mild Steel Bolts Grade 8.8 and Stainless Steel Bolts Grade A4-70Prestressing Force [kN]160.0140.0120.0100.0M 16Frictionmedium80.0M 1260.0W 72/4840.0W 55/42W 53/3420.0W 50/30W 40/220.00.0 50.0 100.0 150.0 200.0 250.0 300.0 350.0 400.0 450.0 500.0T inst [Nm]lowhighM 20Profile Type<strong>Guide</strong> <strong>to</strong> <strong>ETA</strong> compatible Design39

InstallationEfficient, Easy and Fast<strong>JORDAHL</strong> ® supplies anchor channels in all desiredlengths. To avoid fresh concrete from flowing in<strong>to</strong>the profile, <strong>JORDAHL</strong> ® anchor channels are filledwith either polystyrene (PS) or polyethylene (PE)foam. Both types can be removed easily.Connecting<strong>JORDAHL</strong> ® anchor channels are installed according<strong>to</strong> the reinforcement/formwork drawings. Toprevent displacement during concrete pouring, thechannels are held in place:on wooden formwork by nails through the nailholes in the back of the profile, or by lateralbonding with hot melt adhesiveson steel formwork by bonding with hot meltadhesives, or by bolting on with <strong>JORDAHL</strong> ®T-bolts, or with magnetson the surface of a concrete slab by wiring theanchors <strong>to</strong> reinforcement bars or, if required,by means of special spacers spot welded <strong>to</strong> theanchors.ConcreteConcrete is poured, raked and vibrated in<strong>to</strong> theformwork – around the anchor channel concretehas <strong>to</strong> be compacted using appropriate means.Removal of Foam FillerAfter the removal of the formwork the foam fillercan be easily removed by means of a hammer orother <strong>to</strong>ols.Mounting Connections<strong>JORDAHL</strong> ® T-bolts can now be inserted in<strong>to</strong> theanchor channel slot at any desired point and,following 90° rotation, can be fixed by tighteningwith the appropriate <strong>to</strong>rque.

<strong>JORDAHL</strong> ® <strong>Anchor</strong> <strong>Channels</strong>Safety of Designfor Fastenings in Concrete – Based on CEN/TS 1992-4-3: <strong>Anchor</strong> <strong>Channels</strong>With the European countries officially introducingthe CEN/TS 1992-4-3 standard for anchor channels,a completely new developed design conceptis now available <strong>to</strong> calculate the strength of anchorchannels cast in concrete. This concept is basedon the European partial safety design and theEuropean Technical Approval for <strong>JORDAHL</strong> ® anchorchannels (<strong>ETA</strong>-09/0338). It generally leads <strong>to</strong> animproved utilisation of connections with<strong>JORDAHL</strong> ® anchor channels and offers more flexibilityin the design.The following individual conditions can be takenin<strong>to</strong> account for the design of JTA anchor channels:Edge DistanceLength of channelLoad positioning along the channelConcrete StrengthAdditional reinforcementThickness of concrete memberThe consideration of the above mentioned influencesallow <strong>to</strong> tailor-made the design for thespecific needs of each project. The key-benefit ofthis design concept is <strong>to</strong> reach the optimum ofeconomic and technical efficiency.In order <strong>to</strong> keep the effort of the design as small aspossible <strong>JORDAHL</strong> ® has carried out thousands ofcalculations. Taking all theoretical failure modesin<strong>to</strong> account the results have been summarizedin<strong>to</strong> 2 sets of influences: load configuration andgeometry for steel and concrete. With the knowledgeof the corresponding strength and reductionfac<strong>to</strong>rs (see page 13 – 27) any static designer cando a hand calculation.THE EUROCODE DESIGN CONCEPT: F Ed ≤ F RdToday’s building structures are usually designedaccording <strong>to</strong> the concept with partial safety fac<strong>to</strong>rs.The concept is published in the Eurocodes (EC)and was adopted by all national standardizationorganizations in Europe.The design verification according <strong>to</strong> EC2 (concrete)or EC3 (steel) takes place on the design level.The design method according <strong>to</strong> the Eurocode conceptis as follows: The design loads F Ed are loadsfac<strong>to</strong>red with various partial fac<strong>to</strong>rs dependingon the load characteristic (e.g. dead or live load)and probability of simultaneous occurrence (loadcombinations).The design loads are compared with the designresistance F Rd = F Rk /γ M where F Rk is the characteristicresistance and γ M is a specific partial fac<strong>to</strong>r forthe material property (e.g. concrete γ Mc = 1.5, rebarsteel: γ Ms,re = 1.15).In general the proof according <strong>to</strong> this safety conceptis stated as:F Ed ≤ F Rd orF EdF Rd≤ 1Both sides, load and resistance, require more effortfrom static designers than the simplified andmore uneconomic permissible loads design, as youcan see from the adjacent symbolic diagram.However, the procedure allows the designer <strong>to</strong>take different influences of load and material in<strong>to</strong>account and achieve a more constant and reliablesafety level.This state-of-the-art design for anchorage inconcrete is now available as JTA-<strong>JORDAHL</strong> ® anchorchannel software.50<strong>Guide</strong> <strong>to</strong> <strong>ETA</strong> compatible Design
