Staad V8i - Multiple Support Conditions
Staad V8i - Multiple Support Conditions
(OP)
Hi,
Does anyone know if Staad can cope with multiple support conditions within the same model. We do a lot of work on large steel welded modular structures which have 3 or four support conditions throughout their fabrication, sea transportation, lift condition and final in-place foundation arrangement.
Historically, we have created one model and then used "save as" to create parallel models with different support arrangements. The problem is, you end up with 3 or four files and as you run each analysis and have to update members, you have to copy them backwards and forwards to the other parallel models. This is also a pain if you need to alter geometry or insert or remove members. Keeping track of it all and keeping the models consistent is almost a job in itself.
I was wondering if there's any way to model all of these support conditions and code checks within one model so changes to member sizes and inserting/deleting members is done once only.
Hope this makes sense!
Cheers,
Bob

Anyway is time consuming.
Good luck.

I have done something similar to this with a building to simulate the effect on a structure if a column section was removed by a bomb.

I feel your pain. We have the same situation but we also may have more or less parts attached depending on if it's an operating, lifting, or shipping condition. The orientation can also change during shipping and lifting. If anybody ever wrote a program that would truly handle all these variations within one model it would be a boon to mankind. Right now I'm working on a project that has 4 STAAD models for one piece of equipment, operating, shipping, horizontal lift, 45 deg lift, and vertical lift. It's a pain in the . . . well, you know.
