Hello,
I am currently modeling a large structure that consists of a large building column and a crane column being bolted together every 24" o.c.
My question is how to properly model this situation in Staad.
I did try using pin connected angles every 2' but this did not seem to affect the design.
Next I tried some moment connected W beams every 20' and that has shown improvement but some of these connecting beams have failed unity. I am not sure if using this method is an accurate representation of the 2 columns being bolted together, and if so how to choose the members and spacing that I can accurately reflect real conditions and therefore design the bolts and spacing needed.
Thanks for any advice.
