Which structural concept uses a skeleton of vertical and horizontal members to form a rigid frame for buildings?

• A. Frame trabeated
• B. Truss
• C. Masonry arcuated
• D. Neolithic Period

Answer: (A)

Frame trabeated structures rely on a skeleton of vertical columns and horizontal beams that form a rigid frame for the building. This frame carries loads through bending and shear in the members and their connections, allowing open spaces between supports. A truss, by contrast, uses a triangulated network of members—diagonals included—to distribute loads, which is a different way of achieving rigidity. Masonry arcuated refers to arches in masonry, transferring loads primarily through compression in curved forms, not a straight frame. The Neolithic Period is simply a time frame, not a structural concept.
