Hello Jacky89,
I do not know of any specific software features required for pipelines crossing a seismic Fault line beyond typcial burried piping and seismic analysis. Would you please provide specifics program features required for this type of analysis beyond that currently available in AutoPIPE.
Q. Would it be appropriate to design fault line crossings by applying an offset to the pipeline?
A. I apologize, but Bentley Technical support cannot advise people on design routing. Recommend searching the internet for related informaiton, example:
www.ssdinc.com/.../Paper_IPC04-0102.pdf
Note: SSD help in development of AutoPIPE's soil modeling engine.
AutoPIPE v9.5 is able to model Ring Buckling but does not have the ability to model global buckling. If there is no axial compressive strain in the buckled pipe, the displacements at the two ends may be completely decoupled in a theoretical sense. Practically, there will be some compressive strain in the pipe and some displacement transfer may happen between the two ends.
Some companies use the following approach to calculate the bucking length:
The bowing height of the buckled length of the pipe can be compared to the deflection of the pipe under gravity and earth cover loads to determine if the pipe will remain on the ground.
