Problems with calculation of joints

Hi,

 

I’m trying to analysis an A-frame using beam-elements. The A-frame consists of two parallel trusses and one crossbar (see attached file or picture, Att #1). I have problems to calculate the joints in the two trusses. I get endpoint-joints, green joints, at various places in the trusses (Att #3). I want to have only red one, except from the end (as in the picture attached, Att #2). I have tried to vary the clearance between the joints by using the “less than” function.

 

The funny thing is that it works fine to analyze one truss. The problem occurs when I try to analyze the assembly.

 

I would be very happy if some off you could help me with this.
