Z-type steel sheet piles are commonly used in anchor structures, and their strength calculation is similar to that of steel sheet pile walls. Specifically, for hot-rolled Z-type steel sheet piles, the calculated standard load value multiplied by the comprehensive load sharing factor should be less than or equal to the design value specified in the code. For reinforced concrete components, the comprehensive load sharing factor for strength verification should be 1. The comprehensive load sharing factor for crack and crack width calculations should be 0.85.

Anchor walls are typically continuous structures and can be calculated using the method for multi-span rigid-supported continuous beams. The Z-type steel sheet pile tension force RA is used as the support reaction force. The continuous beam can be located in the middle of the wall (vertically). Here, Rer A should be the standard load value multiplied by the tie rod tension unevenness factor = 1.35, that is, RA = RA = 1.35RA.

If the anchor plate is continuous, the calculation is similar to that for hot-rolled Z-type steel sheet piles. If multiple tie rods share a single plate, the beam is calculated as a multi-span rigid-supported continuous beam, and the plate surface is calculated as a cantilever plate at both ends. When one tie rod corresponds to one plate, if a nose bridge is provided, both the beam and plate are calculated as cantilever plates. If no beam is provided, punching verification should be performed in addition to the plate, and reinforcement bars should be installed near the tie rod holes.

Horizontal displacement of the anchor wall or plate can be calculated according to relevant specifications. The length and internal forces of anchored single piles and sheet piles can be calculated using the calculation method for unanchored sheet pile walls under concentrated horizontal forces Ra. Hoesch Z-type sheet piles are manufactured by ThyssenKrupp.
