Combined walls with CAZ box piles - CAZ/AZ
Combined walls built up with CAZ box piles and standard double AZ sheet piles. There are several combinations possible to achieve high bending moments and moment of inertia.

Notes

Notes
- the equivalent elastic section modulus shown in the tables is for the element that takes the largest stresses (lowest equivalent section modulus of the system),
- if the king piles have a different steel grade than the infill sheets, then the stresses in both elements have to be checked separately (with two different equivalent elastic section modulus!!),
- the infill sheet piles AZ are usually lighter and shorter than the king piles,
- the fabrication of the CAZ box piles is quite expensive and time-consuming. It should only be done by experienced welders, based on a specific welding procedure.
