Z type sheet pile is normally used as anchoring structure, and the strength calculation is the same with that of sheet pile wall. In other words, in case of hot rolled Z type sheet piles, the value obtained by multiplying calculated standard load value by comprehensive partial load factor shall be less than or equal to the design value specified in the Code. In case of reinforced concrete member, the comprehensive partial load factor for checking calculation of strength shall take 1.cracking calculation and crack width calculation, comprehensive partial load factor shall take 0.85.
Anchoring wall usually employs a continuous structure. The calculation could be made by the method as used for continuous beam with multi-span rigid support by taking Z type sheet pile pull force RA as support reaction; continuous beam could be arranged at the middle (v tical) of wall. Rer A here should be obtaine by multiplying standard valued of load by non-uniformity coefficient = 1.35 of pull force of pull rod, i.e. RA= RA=1.35RA
If anchoring board is in continuous form, the calculation would be the same with that of hot rolled Z type sheet pile. If several pull rods share one board, the calculation about beam shall be made as continuous beam with multi-span rigid support, and the board surface shall be calculated according to cantilever plates at both ends. When one pull rod corresponds to one board, if nose girder is provided, the calculation of both girder and board shall be made as cantilever plate; in case there is no beam, checking calculation of punching shall be made besides the plate, and the accessories of pull rod hole shall be provided with strengthening rib.
Horizontal shift of anchoring wall or board could be implemented according to relevant specifications. The calculation of length and internal force of anchored single pile and sheet pile could be made by the method as employed in calculation about sheet pile wall without anchor under the effect of centralized horizontal force Ra.
Hoesch Z type sheet piles were produced by Thyssencrupp.
