Steel Connection Design

[SteveG021]

Hi Rafael, 

I am busy learning the steel connection design section. We recently designed a truss structure in RSA but performed the steel connection design using Excel spreadsheet’s and in the future we would like to do the steel connections in RSA.

The model is attached but i am having issues with the connection design. 

I am able to design the foundation and simple connections where there are only two members intercepting a single node. 

My question is how to deal with a connection with more than two members intersecting? 

I get the following error:

 "Incorrect selection or geometry of connections"

Please can you take a look at the model and advise. 

 Would offsetting some of the members help?

Thanks

Steve

My assumption is that you would like to create a connection type as on the picture below. If this is true, then channels are not supported.

Alright.

But i was also looking at the node intersections where there are three or more members interesecting at the same node.

For instance where the cross bracing, column and beams intersect. How would you design such a connection?

Also when you have a column and two horizntal beams connecting at right angles?

Thanks

Could you mark the intended bar selection on the model?

[SteveG021]

You can design each connection individually but i am concerned that all that loads should be taken into account when designing the connection.

Regards

The Steel Connection module is not capable of recognizing such complex connection type. In such case you may want to model this connection as panels and check its behavior in details as suggested in some posts by StefanoPasquini6790.
