Definition of Support Failure

Supports contributing to a load reduction only under compression or tension can be defined as nonlinear supports in RFEM and RSTAB. It is not always easy for the user to select the correct nonlinearity for "failure under tension" or "failure under compression".

Since the support definition must be generally valid, the nonlinearity specification always refers to the coordinate system X',Y'Z' of the support.

If you define a support with "Failure if PZ' negative", the support fails if the "acting support force" acts against the axis Z' in relation to the support coordinate system.

"Failure all if PZ' Negative" Nonlinear Support

If you define a support with "Failure if PZ' positive", the support fails if the "acting support force" acts in the direction of the axis Z' in relation to the support coordinate system.
