Greetings!
Does anyone know if Caesar can perform dynamic analysis on a buried pipeline per B3.4?
I'm working on a relatively long pipeline (about 2000' long, API 5L X65). Most portion of the pipe is buried and has several 3R bends. I'm particularly asked to use B31.4 and not to use B31.3. (DOT permitting requirements, etc). One of the issues that I'm facing in this case is that the buried pipe crossing various areas that have different seismically induced settlements ranging from 2" to 12"(absolute). It seems that is very tedious work to assign this displacements to each individual supports (about 200 supports that been produced through soil modeler) and perform static analysis. My idea was to perform dynamic analysis and determine ISM's to each group of supports. The issue I’m running in to is that the software is giving me the following message and does not calculate any code stresses.
"Dynamic code stress summation cannot be performed for offshore or PD 8010 at this time"
I’m using version 2017 of the software.
Thanks in advance for your inputs.
