A truss is a deep beam with the unused middle removed.

- Patterns to know: Warren — alternating diagonals, Pratt — diagonals in tension, Howe…
The Vierendeel has no triangles, so its joints carry bending. It is heavier, and used where an opening is needed.

- Who is the Trusses poster for?
- Trusses belongs to the Architecture section rather than to a school year, because design is not something one grade owns. Anyone learning structure can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Trusses poster?
- Use it when the span passes about 12 m and a solid beam becomes absurdly deep. A wall chart earns its place by being glanceable from where the work is happening, so Trusses belongs on the wall where that design work actually happens, within glancing distance, rather than filed away.
- What other posters go with Trusses?
- Arches, Vaults and Domes, How a Beam Works and Cantilevers sit alongside Trusses in the Architecture section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Arches, Vaults and DomesHow a Beam WorksCantilevers
- Is the Trusses poster free to download and print?
- Yes. Trusses downloads as a free PDF with no account, no email and no watermark, like everything else in the Architecture section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Trusses poster print at?
- Trusses is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Trusses loses nothing.Printing guide
