Hello, I am making designs similar to the file I uploaded in order to do steel works with idecad. My questions are as follows; I want to add a connection for 1-stabilized beam, but I can't add a connection to the end trusses. The program wants a 3rd element (while adding this connection in the middle; I was choosing the truss and the beams at the other two ends and creating the connection, but it does not occur because there is a truss and a single steel beam at the ends). .I couldn't do it or is there a problem with the program? 2- When I get the steel report, although I increase the purlin section each time (I even used box.70.6 profile and I think the section is too much for this opening), I still get the error "deflection exceeded". Is it due to lack of connection or is there another problem. Other than that, is there a design or add-ons you can suggest for such a cage? Thank you :)
 
Hello there; In your previous messages, Ms. Nurgül made a suggestion to you about lovers, and you did not take it into account. To repeat, if you define your purlins as continuous at once by choosing the trusses at the beginning and end of the building, it will produce more economical sections. In the current project, you have defined the simple purlin the hard way by defining the purlin between each scissors one by one. In this case, the opening moment of your purlins increases and causes you to use larger sections. In addition, 150kg/m² live load is defined on your roof covering, if people will not walk on the roof or if no other equipment will be placed on the roof, you should delete this load. This is the main reason why the sections are large. Best regards.
 
Thank you very much for the reply. I understand what you want to say, I am getting these errors due to the definition of load and lover. but I can't create a connection to the end trusses for the stabilized beam. It wants the 3rd object, how can I do this, am I doing something missing or is there a problem in the definition, how do I do this?
 
Hello there; You don't have to select the 3rd element to define the joint. When defining the cross-end joint, first select the stability beam, then the truss top cap and complete the joint with the right button. In the model I sent you, I did this operation and the union seems to be defined, you can also examine the model. Good work.
