Steel Space truss design
(OP)
Dear all
anyone has design calculation for space 3d truss can share it with me, please.
is it the same as normal trusses or it needs a special requirement?
and the joint ball which is collecting the members(kindly refer to the attached, how we can design it?
Thanks
Maher

Space trusses are best left to proprietary suppliers. I wouldn't even attempt a one off system.
RE: Steel Space truss design
-You may model the 3D space truss with FEM ( with using SAP 2000 or similar software ) assigning the joints free to rotate.
- But i will suggest you to ask the services of the supplier since this trade is specialized field and they provide design calc. when you choose as supplier..
- I remember collapse of HARTFORD CIVIC CENTER COLISEUM. Pls have a look to the following doc. to see the modelling issues..

Not sure what you mean. I don't think that SI units would have been involved at all in the 1970 design. If you mean those MN, GN forces listed in the article table, yes, the writers are confused about how SI is intended to be used. And yes, their conversions are off by a factor of 1000. Someone should tell them that units of force, for structural engineering purposes, should be expressed in kips in the US, kN elsewhere.

But I do suspect that using kg as the base unit, instead of g, confuses some people.

The authors of that paper should be ashamed, as should the editors. I suppose a correction is too difficult now, as the paper is more than 20 years old.

According to your post , although your favorite software is ABACUS , i am not sure if you can really use it ..But apparently you are capable with photoshop.
The original picture of the subject ABACUS is,
