A cantilever is a Beam supported on only one end. The beam carries the load to the support where it is resisted by Moment and Shear Stress . Cantilever construction allows for overhanging structures without external bracing. Cantilevers can also be constructed with Truss es or Slab s. This is in contrast to a simply supported beam such as those found in a Post And Lintel system. A simply supported beam is supported at both ends with loads applied between the supports. IN BRIDGES, TOWERS, AND BUILDINGS Cantilevers are widely found in construction, notably in Cantilever Bridge s and Balconies . In cantilever bridges the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is a famous example of a cantilever truss bridge. Temporary cantilevers are often used in construction. The partially constructed structure creates a cantilever, but the completed structure does not act as a cantilever. This is very helpful when temporary supports, or Falsework , cannot be used to support the structure while is is being built (e.g., over a busy roadway or river, or in a deep valley). So some Truss Arch Bridge s (see Navajo Bridge ) are built from each side as cantilevers until the spans reach each other and are then jacked apart to stress them in compression before final joining. Nearly all Cable-stayed Bridges are built using cantilevers as this one is one of their chief advantages. Many box girder bridges are built Segmentally , or in short pieces. This type of construction lends itself well to balanced cantilever construction where the bridge is built in both directions from a single support. In an architectural application, Frank Lloyd Wright's Fallingwater used cantilevers to project large balconies. The Roof built over the stands at Old Trafford Football Ground uses a cantilever so that no supports will block views of the field. |
