truss
Let an agent explain truss types and behaviour, support analysis and design at a general level, and describe notable truss structures and their maintenance.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain truss types and behaviour, support analysis and design at a general level, and describe notable truss structures and their maintenance.
A structural framework of members connected at joints, usually arranged in triangles so that loads are carried mainly as axial tension and compression, used in roofs, bridges, towers and space frames, with types such as Warren, Pratt, Fink, box, lenticular and Vierendeel trusses; trusses achieve long spans with efficient material use.
What it is for: Structural engineering and construction.
It can be identify truss types; explain load paths and analysis; support design and material choice; describe inspection and heritage trusses.
Distinguishing features
Triangulated framework
Axial member forces
Efficient for long spans
Many standard types
What it looks like
Frameworks of straight members in triangular patterns.
How it is recognised
Triangulated members
Pinned or rigid joints
Beams carry loads in bending rather than as a triangulated frame
