SUMMARY

This discussion focuses on the process of drawing N-, V-, and M-diagrams for structural analysis, specifically in the context of a structure involving simply supported beams AD and DB. Participants clarify that the structure is not unstable and emphasize the importance of understanding how loads from slabs are transferred to beams and then to trusses. The conversation highlights the need for tutorials to aid in accurately creating these diagrams, particularly in non-standard cases.

PREREQUISITES
  • Understanding of structural analysis principles
  • Familiarity with simply supported beams
  • Knowledge of load transfer mechanisms in structures
  • Experience with drawing shear and moment diagrams
NEXT STEPS
  • Research tutorials on drawing N-, V-, and M-diagrams for complex structures
  • Study the behavior of simply supported beams under various loads
  • Explore advanced structural analysis techniques for trussed beams
  • Learn about stability analysis in structural engineering
USEFUL FOR

Structural engineers, civil engineering students, and professionals involved in analyzing and designing beam structures will benefit from this discussion.

Certainly, this is not a truss, because of q. Can anyone explain how I can draw the N-, V- and M-diagram for the structure?

Does this problem comes with a statement?, usually a roof or slab is supported by beams which receive the load from the slab and then send it to the truss as point loads. This structure as a whole is unstable.

No, there's no statement. But AD and DB is to be regarded as two simply supported beams.
 
Actually, it's not unstable, but you might want to look in our tutorial section, there are a couple of tutorials that explain how to draw the diagrams.
 
I know how to draw the diagrams on normal beams, but not in this particular case.
 
You'll have moments on the AD-DB part only, unless I'm missing something.

That's right. This is a trussed beam (or 2 trussed beams).
