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
Combiwalls CAZ/AZ steel sheet piles
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.
