What term describes the arrangement of structural components forming an internal support system in buildings?

The arrangement of structural components that forms an internal support system in buildings is referred to as a frame. This concept encompasses various interconnected elements, such as beams and columns, that work together to support the weight of the building and resist forces like gravity and lateral loads. The frame is crucial in distributing loads throughout the structure, ensuring stability and integrity.

Frames can be made from various materials, including wood, steel, or reinforced concrete, depending on the design and requirements of the building. They allow for open interior spaces and typically create a skeleton that gives shape to the building.

Other terms like diaphragm, truss, and column system describe specific structural systems or components, but they do not encompass the full arrangement of structural elements as a frame does. A diaphragm relates to a structural element that transfers lateral loads to vertical members, a truss is a specific framework designed to support loads, usually in a way that maximizes strength while minimizing material, and a column system specifically refers to vertical structural elements that support beams and loads but does not account for the overall assembly. Thus, frame is the most fitting term for the internal support system in buildings.
