An A-frame is a basic structure designed to bear a load in a lightweight economical manner. The simplest form of an A-frame is two similarly sized materials laid up against one another, and attached at the top in a convenient fashion. These materials are often wooden or steel beams arranged in a 45-degree or greater angle. These materials are then lashed together with rope, or secured in another fashion such as welding, gluing, or riveting.
Due to having only two "legs", A-frames are usually set up in rows so that they can have good stability. A saw horse is a good example of this structure. More complex structures will have a crossmember connecting the two materials in the middle to prevent the legs from bowing outwards under load, giving the structure the appearance of the capital letter A.
Additional structures that use A-frames:
- A frame camping tent
- Folding ladder
- Double wishbone suspension (cars)
- Some suspension bridges
