3d and 2d modelling of steel pipe rack
3d and 2d modelling of steel pipe rack
(OP)
Hi,
Why pipe racks of modeled in 3d instead of 2d , Since lot of time is wasted in 3d analysis, Can any one specify good answer with justification .

So would you rather have 2 models for each direction or 1 that could encompass both?

In fact pipe racks are actually fairly straightforwards for a simple loads analysis. BUT!
A good 3D design check includes interferences, access, removal, installation, changes to other pipes and systems, and connections details. Other 3D packages do the BOM and sub-set building parts lists, and connection details, and connections accuracy (position, direction, specification, bolt matchup, material, etc.)
Biggest is the continual changes made during the design phases - by piping yes, but also by all of the other groups around piping racks.

If the pipe rack consists of bents that are not connected to each other, a 2D frame analysis is adequate as long as you also include any out of plane loads (normal to pipe rack). Any loads transferred between the bents will have to travel through the piping, cable tray, etc. This will not occur as long as the bent is stiffer than the items on the bent (i.e. 99.99% of the time....I hope)
If the pipe rack consists of a series of bents that are connected to each other, a 3D analysis would be more appropriate because a load on one bent could easily have an effect on an adjacent bent.
