design connections between rhs to existing ub column
hi guyz,
       i am trying to design a roof rack for a friend's small factory, a rhs column bolted onto the side of the ub column ( please refer to the attachement). how do i design the connections between rhs & ub column?
thanks for helping out.  
like this?
yep, that's right. how do i deisgn the bolt size and end plate for it? ..... with v* = 5kn and m*= 5knm
thank you very much. (please refer to the revised jpg file)  
1. are you a structural engineer?
2. how were those loads calculated? as4100 section 9 includes minimum design capacity of connections.
3. the connection as shown will provide a "pinned" connection but would have to be modified to carry moment. (although loads are so small you would probably get away with it.)
4. basics of connection design are covered in asi "design of structural connections"
thank you, where do i find this book that u mentioned? can i grab it off from the internet? sorry, i am not a structural engineer, those loads were calculated using spacegass.  
i would suggest you get a structural engineer to give you a detail.
you can't expect spacegass to give the right answer unless the analysis is done correctly and you need an engineer who understands all the relevant load patterns and combinations to do that. similarly with designing the   
the as 4100 is the australian standards for steel design.
