How much pressure from filling concrete can take the KAP-Steel-Wave?
According the approval ETA-15/0224, Kappema composite wall, the KAP-Steel-Wave was calculated with the global safety factor calculation. In the approval the force for filling concrete is fixed on 9.5 KN / stick in a 55 mm layer.
The maximum possible pressure from filling concrete can be calculated as following:
Number of waves per sqm x 3 Sticks x 13.3 KN / safety factor 1,15
The concreting height depends on the consistency of the filling concrete (hydraulic pressure) and can be calculated with the parameters for this concrete.
Distance of the waves horizontal 78 cm
Distance of the waves vertical 70 cm
Max. height for filling concrete F3 = 3.25 m
Max. height for filling concrete F4 = 2.74 m
It is also necessary to calculate even the layer against the forces from filling concrete in between the waves. This calculation must be done on top.
