Calculation of Vertical parts

For a vertical pipeline part some of the locally applied soil mechanical values actually can be mapped to a different global soil mechanical value.

Example:

The downward vertical soil stiffness [KLS] for a vertical pipeline part is actually the Horizontal soil stiffness [KLH] of the soil. 'Downward' for a vertical pipeline is oriented horizontally.

 

For vertical parts the different soil mechanical values are set as follows:

No reduced Ultimate top soil reaction is used. The bold values indicate the differences compared to a 'normal' calculation.

For (near) exact vertical elements, the local y-axis is defined parallel to the global y-axis.
