Dear All,
I am doing static analysis of a complete buried pipe, code B31.4.
If I run the analysis with 25 barg as P1, the output in Caesar give me allowables for operating load case, hence i have a certain value for the code stress ratio.
If I increase P1 from 25 barg to 27.3 barg, Caesar's output doesn't yield anymore allowables for operating case.
Why?
Thank you
