What is the name of the area created in the triangles used to create trusses?

• A. Web Space
• B. Chord Space
• C. Truss Core
• D. Open Web Space

Answer: (D)

The area formed by the triangulated web inside a truss is called the open web space. In an open web truss, the top and bottom chords are linked by web members that create a series of triangles, and the spaces between these members become voids or openings. These openings are specifically described as open web spaces, highlighting both the “open” nature of the web and the spaces created by the triangular arrangement. This term helps distinguish them from solid or closed areas and from other vague phrases like “web space” or “chord space.” The term captures the characteristic openings produced by the triangular web pattern, which also explains why such trusses are valued for reduced weight and the ability to pass services through the openings.
