The yield moment is used for calculating the horizontal limit load of the micropiles. An instrument is specially provided for calculating the yield moment. The environment for the calculation of the yield moment is the following:
Environment for the calculation of the yield moment of the micropile
The diagram to refer to is the following:
Geometry of the section and solicitation convention
The data to be entered are the following:
Outer diameter (De):
The outer diameter of the section, expressed in mm;
Tubular rod thickness (t):
It is the thickness of the sheet constituting the tube, expressed in mm;
Yield stress:
It is the limit yield stress for the calculation of the moment. This data is adequate since it assumes a constitutive rigid plastic binding for the material.
Normal stress:
It is the outer normal stress in whose correspondence to determine the yield moment. It is expressed in kN
Yield moment:
It is the yield moment searched for. It is expressed in kN per m.
According to the convention, the normal stress is positive when due to compression and the bending moment is positive if it strains the lower fibres of the section.
