Basic rules for modeling intersections between beams in CEDRUS.

In many occasions, when a complex truss of beams is arranged in a CEDRUS model, it is very likely to make mistakes in the intersections between these elements.

If we look at section B 8.7.4 of the CEDRUS-8 manual, we see the following:

 

 
If we look specifically at the second figure above:
 

 

We see that it is not possible to cross more than 2 beams.

In the following example, the curved beam is formed by a succession of beams one after the other, as can be seen by the points that draw it:

 

 
If we extend one of the beams that go to one of the columns, we produce a crossing between 3 beams:
 

 

As the manual indicates, this is not allowed.

In order for the program not to produce this error, it must be ensured that there is only one beam and not two in the arrival zones of the radial beams.

 

In addition, the beam must reach to the rear face, as shown in the figure above and indicated in the manual:
