creating a hole in circular hollow cylinder
creating a hole in circular hollow cylinder
(OP)
I am using Staad.pro 2007. I am trying to model a vertical hollow shaft with a circular hole on one of its surface. Don't know how to do this in staad.
Any kind of info. on this will be highly appreciated.
Thank you

RE: creating a hole in circular hollow cylinder
As for the hole, you said "one of its surface" (sic). Again I have to assume that you're talking about the curved surface since you didn't say, and I'm just imagining a single pipe of constant diameter with no end caps.
For this you would have to manually remove elements and move nodes to create the hole. As I said, STAAD is not very sophisticated for this sort of thing. If you did a lot of this sort of modeling you would need something like COSMOS/Works or Algor

However, if the boss is ALL you're modeling, you can get away from the no-curved-element trap by using very small elements. I would use the 3D brick-type or SOLID elements (as they're called in STAAD). The easiest way is to build up a wireframe with beam elements, just to establish the nodes in space, then come back and delete those once you "connect the dots" with the solid elements. Otherwise, you can also just import a 3D DXF from a CAD program like Autocad or Pro/E (may need a go-between).
There's nothing to it. You can do anything in STAAD. It's our minds that have to accommodate the scale of the work that is required.
