As we find in the current version of CAESAR II 5.20 that it gives the check for allowable stresses only with restraint case option on for B 31.8. My question is we have system partly abovegound and partly underground. Where the aboveground section is with restrained off and the burried section with restrained on. Under such scenario how the stress shall be checked.


Also we have one more query, we find some results that shows the stress check for expansion case also in B 31.8 case. However on further checking we find that if the restrained made on the problem is rectified.

Can some body provide guideline on this

You have control over the "restrained" versus "non-restrained" portions of the piping system. Check the Quick Reference Guide to see the equations used for B31.8, and when the OPE equation is necessary and when the SUS/EXP equations are necessary.

In the future could you please:
a) Start a new thread for a new topic
b) Post in the proper Forum. This post should have been a new thread in the CAESAR II forum.

Thank you.
