Cantilever

Definition

A cantilever is a beam or structure that is anchored at only one end, extending outwards without any support at the other end. This design allows for overhangs and extensions beyond vertical supports, making it a critical innovation in architecture as it enables the creation of dynamic and visually striking structures that maximize space and aesthetic appeal.

5 Must Know Facts For Your Next Test

1. Cantilevers were popularized in modern architecture during the late 19th and early 20th centuries as new materials like steel and reinforced concrete became available.
2. The use of cantilevers allows for open floor plans and creates dramatic roof overhangs, enhancing both functionality and aesthetics in buildings.
3. Famous examples of cantilevered structures include Frank Lloyd Wright's Fallingwater and the Guggenheim Museum in New York, showcasing the versatility of this design.
4. Cantilever construction requires careful calculation of loads and forces to ensure stability, as improper design can lead to structural failure.
5. This architectural technique has influenced not only buildings but also bridge design, allowing for long spans without the need for numerous supports.
