7 APPENDIX D Operation yles Strandjak unit In this appendix a review is presented on two main operation yles of the strand jak unit SSL to familiarize the reader with the general onepts of the Strand jak-unit SSL.: Jak up yle (lifting the load) Jak down yle (lowering the load) D.1 Jak up yle (lifting the load) In the next paragraph the Jak up yle of the hydrauli Strand jak units is desribed. This priniple onerns all types. START POSITION STEP 1 WEDGE UPPER ANCHOR HEAD RELEASE PIPE UPPER RELEASE CILINDER UPPER RELEASE PLATE WEDGE LOWER ANCHOR HEAD RELEASE PIPE LOWER RELEASE CILINDER LOWER RELEASE PLATE STROKE LOAD LOAD STROKE Figure 9: Start position and Step 1 of the Jak up yle The start position (see Figure 9): The 18 mm dyform ompat strands are installed through the unit and the load is onneted. Both upper and lower anhor heads are loked (red in Figure 9). Step 1 (see Figure 9):The piston of the jak extends and raises the upper anhor head inluding the loked strands and onneted load. During this movement the wedges in the lower anhor head are pulled up slightly by the movement of the strands; the lower anhor head is still losed. In ase of failure of the upper anhor head, the wedges in the lower anhor head seure the load. Researh strand jak wedges Appendies By H.G.M.R. van Hoof 7
8 STEP 2 STEP 3 STROKE -15 mm LOAD LOAD Figure 10: Step 2 and Step 3 of the Jak up yle Step 2 (see Figure 10): In top position the load is transferred from the upper anhor head to the lower anhor head by slightly retrating the piston, approx. 15 mm. During this load transfer both anhor heads remain loked. Step 3 (see Figure 10): After the transfer, the upper anhor head is opened hydraulially. The upper release ylinder lifts the release plate with the release tubes and shifts the wedges/grips up and of their seatings (Note the differene between left and right detail piture).the upper anhor head is now unloked (blue in Figure 10) allowing free passage of the strands.

The strands slide through the wedges in the upper anhor head. Step 5 (see Figure 11): At the end of step 4, the upper anhor head is loked again by the upper release ylinder retrating the release plate and release tubes. The jak up yle of step 1 to 5 is repeated till the required jak up distane is aomplished. Researh strand jak wedges Appendies By H.G.M.R. van Hoof 9
10 D.2 Jak down yle (lowering the load) In the next paragraph the Jak down yle of the hydrauli Strand jak units is desribed. This priniple onerns all types. START POSITION WEDGE UPPER ANCHOR HEAD RELEASE PIPE UPPER RELEASE CILINDER UPPER RELEASE PLATE STEP 1 WEDGE LOWER ANCHOR HEAD RELEASE PIPE LOWER RELEASE CILINDER LOWER RELEASE PLATE LOAD Figure 12: Start position and Step 1 of the Jak down yle The start position (see Figure 12): The 18 mm dyform ompat strands are installed through the unit and the load is onneted. Both upper and lower anhor heads are loked (red in Figure 12). Step 1 (see Figure 12): The upper anhor head is opened hydraulially. The upper release ylinder lifts the release plate with the release tubes and shifts the wedges/grips up and of their seatings (Note the differene between detail piture of the upper anhor head in Start position and Step1). The upper anhor head is now unloked (blue in Figure 12) allowing free passage of the strands. Researh strand jak wedges Appendies By H.G.M.R. van Hoof 10
11 STEP 2 STEP 3 LOAD LOAD Figure 13: Step 2 and Step 3 of the Jak down yle Step 2 (see Figure 13): With the upper anhor head unloked, the piston of the jak extends till approx. 15 mm before end of the ward stroke (ompare the position of the main hydrauli ylinder in step 1 and step 2). The strands slide through the wedges in the upper anhor head during the stroke. Step 3 (see Figure 13): In the position 15 mm before end of the ward stroke the upper anhor head is loked by the upper release ylinder retrating the release plate and release tubes (red in detail upper anhor head in see Figure 13 step 3). Researh strand jak wedges Appendies By H.G.M.R. van Hoof 11
12 STEP 4 STEP 5 LOAD LOAD Figure 14: Step 4 and Step 5 of the Jak down yle Step 4 (see Figure 14): The load is transferred from the lower anhor head to the upper anhor head by slightly extending the piston of the main ylinder further (approx. +15 mm) to the end of the stroke. During this load transfer both anhor heads remain loked (both red in Figure 14 step 4). During this movement the wedges in the lower anhor head are pulled up slightly by the movement of the strands; the lower anhor head is still losed. In ase of failure of the upper anhor head, the wedges in the lower anhor head seure the load. Step 5 (see Figure 14): After the transfer, the lower anhor head is opened hydraulially ( unloked ; blue in detail of lower anhor head step 5). The lower release ylinder lifts the release plate with the release tubes and shifts the wedges/grips up and of their seatings (Note the differene between left and right detail piture step 4 and step 5).The lower anhor head is now unloked (blue in Figure 14) allowing free passage of the strands.

20 APPENDIX F Malfuntion of the wedge For the benefit of the analysis, three possible ases are desribed to larify the malfuntion of the wedge, aording to the mehanial wedge model: 1. Wedge operation with : µ Constant, inreasing µ k 2. Wedge operation with : µ k Constant, dereasing µ 3. Wedge operation with : Inreasing µ k, dereasing µ In the following paragraphs these load ases are desribed in detail. F.1 Wedge operation with : µ Constant, inreasing µ k When the wedge operation is started, a proper and normal operation of the wedge is assumed.this implies that the frition onditions are below the good/bad borderline in Figure 20. For example, fitive estimated start values of µ k and µ in operation are 0,2 and 0,5 (see start operation point A in Figure 20). 0.6 Frition oeffiients 0.4 Malfuntion of wedge (slipping of strand, situation 2) B ` µ k 0.2 A Wedge operating properly (situation 1) α =8.19 µ Figure 20:Wedge operation with inreasing µ k With inreased µ k, the operation point B is positioned in the red Malfuntion Area.The frition fore between wedge er surfae and tapered hole surfae is too high and onsequently gripping ation is less; the strand slips through the wedge. Researh strand jak wedges Appendies By H.G.M.R. van Hoof 20
21 F.2 Wedge operation with : µ k Constant, dereasing µ When the wedge operation is started, a proper and normal operation of the wedge is assumed. For example, fitive estimated start values of µ k and µ in operation are 0,2 and 0,5 (see start operation point A in Figure 21). 0.6 Frition oeffiients 0.4 Malfuntion of wedge (slipping of strand, situation 2) µ k 0.2 C A Wedge operating properly (situation 1) α =8.19 µ Figure 21: Wedge operation with dereasing µ When µ dereases during operation below the value 0,35 and the value µ k is onstant, the operation point of the wedge is moved from A to point C (see Figure 21 ). Operation point C is positioned in the red Malfuntion Area.The frition fore between wedge inner surfae and able surfae is too low, onsequently the gripping ation is less; the strand slips through the wedge. F.3 Wedge operation with: Inreasing µ k, dereasing µ In most pratial ases the values of the frition oeffiients will hange simultaneously, influened by environmental irumstanes (temperature, relative humidity et.). Researh strand jak wedges Appendies By H.G.M.R. van Hoof 21
22 A ombination of inreasing µ k and dereasing µ will lead to mal-funtion of the wedge onform Figure 22, the operation point of the wedge is moved from A to point D. Malfuntion of the wedge appears. 0.6 Frition oeffiients 0.4 Malfuntion of wedge (slipping of strand, situation 2) D 0.2 A µ k Wedge operating properly (situation 1) α =8.19 µ Figure 22: Wedge operation with dereasing µ and inreasing µ k Researh strand jak wedges Appendies By H.G.M.R. van Hoof 22
23 APPENDIX G Miro slip during jak up In every load yle (jak up and jak down) miro slip will our in the wedges of the upper and lower anhor head. This is a result of the differene in axial strain (as a result of the load fore F L ) between the able and wedge in onsequene of the differene in stiffness. The axial strain in the able is larger than in the wedge. Hene the strain in the loaded able an not be followed by the wedge what results in a relative displaement between the able er surfae and wedge inner surfae. Miro slip in ombination with a load fore results in wear of the inner frition surfae of the wedge and eventually in a redution of the inner frition oeffiient µ. Finally this will ause malfuntion of the wedge. When the piston of the jak extends, the losed upper anhor head is raised inluding the strands. The load fore F L and related strain in the strand inrease during this movement until the anhor head bears the total present load fore F L. The situation of the full loaded wedge in the anhor head is desribed shemati in Figure 23. F L = Load fore V = Spring fore (pre-stress) Figure 23: Loaded wedge during raising of upper anhor head Researh strand jak wedges Appendies By H.G.M.R. van Hoof 23
24 N in = Normal fore on inner wedge surfae µ = Kineti oeffiient of frition on inner wedge surfae Q = Length ar of wedge part α = Wedge angle σ w = Compressive stress between wedge and able σ = Tensile stress in able as result of F L ε = Strain in able S = Position of slip front L = Length of frition profile A able = Cross setion area of able E = Modulus elastiity of able τ w = Frition shear stress At the end of the trajetory of the inreasing load fore F L (the upper anhor head bears the total load fore F L ), the slip front has propelled to distane S. In the ross setion of the able on position S, the tensile stress σ = 0. Along the inner frition surfae of the wedge part, width Q and length L, exists a ompressive stress σ w between wedge and able as a result of the normal fore N in. The (pre-stress) spring fore V is negleted and the stiffness of the wedge is onsidered infinite in the following onsiderations. This ompressive stress σ w present on the 3 wedge parts is formulated as: σ w = N in 3 Q L The ompressive stress σ w is able to transmit an average frition shear stress τ f on the ontat area: τ = µ σ w w The load fore F L is ompensated by three inner frition surfaes, with an area of Q s and thus is derived for F L : F L = 3 Q s τ w = 3 Q s µ σ w 3 Q s µ N = 3 Q L in = s µ N L in A inreasing fore F L results in a inreasing value of s, as soon as s > L total slip and F L = F max = µ ours. N in If s > L : maroslip ours, the strand slips through the wedge If 0<F L <F max : miroslip ats along length s. For the tensile stress σ and strain ε in the able we an write σ = F A L able ε σ = E = E FL A able The length s an be alulated from the relation s = µ FL N in L (Eq. G.1) Researh strand jak wedges Appendies By H.G.M.R. van Hoof 24
25 The tensile stress aording to σ diminishes linear with values on positions x = 0 to x = s (see Figure 23 ) σ = 0 and (x 0) = σ (x = s) And analogially with the equations for the tensile stress σ 0 ε (x= 0) = = = 0 and E E A able ε (x= s) F = A L able A graph of the x- position against strain ε is provided in Figure 24. σ, equations for strain ε are σ FL = = E E A able Figure 24 Graph of position x, strain and tensile stress in able wedge With usage of Figure 24 the total able elongation dl in the wedge is derived. The elongation dl of the able in the wedge orresponds with area P 1 dl = P = ε (x= s) s 2 With σ L ε (x= s) = = and E E Aable F FL L s = µ N in After substitution, dl beomes Researh strand jak wedges Appendies By H.G.M.R. van Hoof 25
26 dl 1 2 = ε(x= s) s = 2 E F A 2 L able L µ N in Funtion ε (x ) an be desribed as (see Figure 24 ) F x L ε (x) = for 0 x s E Aable du ε dx du FL x = dx E A With the definition = (x) follows able To obtain the loal relative displaement funtion u(x) du FL x u(x) = [ ] dx = [ ] dx dx for 0 x s E A able This leads to the relative displaement funtion u(x) 2 FL x u(x) = + C for 0 x s 2 E A able With u (0) = 0 onsequently C = 0, relative displaement funtion u(x) beomes F u(x) = 2 E L x A 2 able for 0 x s (Eq.

27 Equation G-2 is presented graphially in Figure 25. Figure 25: Graph of relative displaement u(x) of the er able surfae against inner frition profile The magnitude of relative displaement u(x) (and thus wear) of the er able surfae against the frition profile depends mainly on the loation of the slip front S, assuming F L, A able, E onstant. Maximum slip is loated at the loaded let of the able at position S. Researh strand jak wedges Appendies By H.G.M.R. van Hoof 27
