Detailed radial deformations of pipe cross-section (material non-linear analysis) (Output Table)

Data description/Result options:

ANGLE:

Location at circumference where calculations have been performed

(Measured in positive sense around x-axis from y-axis.)

W-GROUND:

Detailed radial deformation of pipe wall due to soil reactions

W-BEND:

Detailed radial deformation of pipe wall due to ovalisation of bend caused by bending moment

(Undefined if ELEM is not a bend element.)

W-ELAS:

Detailed elastic part of total radial deformation of pipe wall

W-PLAS:

Detailed plastic part of total radial deformation of pipe wall

W+WD/D:

Detailed change of diameter (in %) due to loads on cross-section

(The outer diameter is used.)

W-TOTAL:

Detailed total radial deformation of pipe wall

RG/KLG:

Elastic impression of the soil at 50 % of 'horizontal' bearing capacity ¹

(RG is 50 % of RH or (RVS+RVT)/2 whichever has the lowest value, KLG is KLH or (KLS+KLT)/2 whichever has the lowest value.)

KLG:

'Horizontal' bedding constant (soil stiffness) ¹

(KLG = KLH or (KLS+KLT)/2 as long as W-TOTAL is less than or equal to RG/KLG. If W-TOTAL > RG/KLG, KLG decreases. KLG is a bilinear soil spring.)

AX_BUCKL:

Detailed axial buckling strain as a percentage of the critical one

EXT_PRESS:

Detailed percentage of critical strain due to external pressure

 

¹ These quantities are reported only if the Soil Ring-Stiffening Option is Applied. The bilinear soil spring KLG is attached to those points of the crosssection which move to the outside due to the ovalisation. The average soil parameters are taken, so without uncertainty factors. The maximum soil resistance (RG) taken into account is 50 % of the lowest bearing capacity. If RVT = 0, no horizontal soil support springs will be applied.
