Problem:
How can the axial force in the pipe steel be extracted from AutoPIPE's Output file?
Solution:
AutoPIPE has a feature to export the Global or Local Forces and Moments values in the Output report. Suggest using the Local reporting method instead of the Global reporting method. Local reporting is beneficial on extracting the axial forces in the pipe steel regardless of pipe orientation and skewed axis.
From AutoPIPE help:
Force (Global/Local)
Enter the code letter for the coordinate system to be used to report (pipe) force and moment data. Accepting the default, G, produces force and moment data relative to the global axes. Entering L will produce force and moment data relative to the local axes. Refer to Results Interpretation for details related to the orientation of these systems.
If using linear analysis, simply create a combination (or use an AutoPIPE default combination) that does not contain internal pressure load cases and obtain the axial force, which is in the local X-direction.
If using Non-linear Analysis, remember Load Sequence rules and be mindful of creating combinations with or without Pressure Extension. Ideally, use AutoPIPE default combinations to be safe,

Question:
How to print a General Stress report that would allow axial stress at a section to be correlated with axial force in the pipe steel at the same cross section. Is this possible?
Answer:
Please see the following AutoPIPE help section:
Help > Contents> Contents Tab> Reference Information> General Stress Calculations > Longitudinal Stress
Removing pressure from the combination will disable the pressure component mentioned in the note at the bottom of the page.
