With:

  • EI = bending stiffness = modulus of elasticity [kN/m2] × moment of inertia [m4/m]
  • System width = external diameter [mm] + width sheet piles [mm] + 50 mm
  • System weight = (weight pipe [kg/m] + weight sheet pile [kg/m] × length sheet pile / length tube) / systeem width [m]
    *weight of interlocks on tubes not included
  • Bending moment = elastic section modulus [m3/m] × minimum yield strength [kN/m2] (without safety factor)

Remark:
The decimal symbol of the input can be a point or a comma. The decimal symbol of the output is a point.
The use of digit grouping symbols is not allowed.
