Tubes and combined walls

Input parameters

Steel grade

External diameter (mm)

Wall thickness (mm)

Length (m)

Number of tubes

Results

Moment of inertia (cm⁴)

Section modulus (cm³)

Weight (tons)

Bending moment* (kNm)

* Bending moment = elastic section modulus [m³] x minimum yield strength [kN/m²] (without safety factor)

Input parameters - Tubular piles

Steel grade

External diameter (mm)

Wall thickness (mm)

Length (m)

Results

System width (mm)

Moment of inertia (cm⁴)

Section modulus (cm³)

System weight* (kg/m2)

Input parameters - Intermediate piles

Sheet pile profile

Length (m)

EI (kNm²/m)

Bending moment (kNm/m)

EI = bending stiffness = modulus of elasticity [kN/m²] x 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] x length sheet pile / length tube) / systeem width [m]
* weight of interlocks on tubes not included
Bending moment = elastic section modulus [m³/m] x minimum yield strength [kN/m²] (without safety factor)

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