Frame

Definition

A frame is a structural system consisting of relatively long, prismatic members fastened together. A rigid frame is one in which the joints can transmit moments as well as forces and does not require a braced frame for rigidity.

Purpose

The purpose of a frame is to provide the skeletal structure of a building, supporting loads and maintaining the overall shape and integrity of the structure. Rigid frames offer stability and strength, allowing for the construction of open, unobstructed spaces.

Examples of Use

• Steel frames are commonly used in the construction of skyscrapers and large industrial buildings, providing a strong and flexible structure.
• Wood frames are typical in residential construction, forming the skeleton of the house, including walls, floors, and roofs.

Related Terms

• Braced Frame: A frame system that uses diagonal bracing to provide additional stability and resistance to lateral forces.
• Truss: A framework of triangles used to support roofs and bridges, distributing loads efficiently.
• Load-Bearing Wall: A wall that supports vertical loads from the structure above, in contrast to a frame that supports the building's weight.

Notes

Frames must be designed to withstand various loads, including dead loads (permanent, static forces) and live loads (temporary, dynamic forces such as wind or occupants). The choice of framing material and design depends on the specific requirements and conditions of the project.
