Problem:
Typical question / issues with AutoPIPE's Output "Results Summary" Sub Report
Questions / Issues:
- Model is producing the following warning in the Results Report:
Maximum displacement stress ratio = zero
Answer:
This is correct if the model meets the following criteria:
A. Model/Segment does not contain any bends
B. Under Tools> Model Option> Results> Include axial force is disabled (checked OFF).
Note: See the online help for information on Results Option: "Include axial force".
Under these conditions, the pipe is free to move in the axial direction without any resistance due to friction on the supports. In addition, the "Include axial force" option is turned off as to not report any stress in the results.
Avoidance:To see a Maximum Displacement stress in a model with no bends and/or "Include axial force" option disabled (checked Off)
A. Under Tools> Model Option> Results> Include axial force is enabled (checked ON).
B. Add friction values to pipe supports and perform a Non-linear analysis which will consider
Gaps/Friction/Soil.
