A cantilever is a rigid structural element that extends horizontally and is unsupported at one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab.
The cantilever method is an approximate method for calculating shear forces and moments developed in beams and columns of a frame or structure due to lateral loads. The applied lateral loads typically include wind loads and earthquake loads, which must be taken into consideration while designing buildings.
A double jettied timber-framed building. The ends of the multiple cantilevered joists supporting the upper floors can easily be seen.. Jettying (jetty, jutty, from Old French getee, jette) [1] is a building technique used in medieval timber-frame buildings in which an upper floor projects beyond the dimensions of the floor below.
A formalized lintel, the lowest member of the classical entablature. Also the moulded frame of a door or window (often borrowing the profile of a classical architrave). Area or basement area In Georgian architecture, the small paved yard giving entry, via "area steps", to the basement floor at the front of a terraced house. Arris
The deflection must be considered for the purpose of the structure. When designing a steel frame to hold a glazed panel, one allows only minimal deflection to prevent fracture of the glass. The deflected shape of a beam can be represented by the moment diagram, integrated (twice, rotated and translated to enforce support conditions).
Wall framing in house construction includes the vertical and horizontal members of exterior walls and interior partitions, both of bearing walls and non-bearing walls. . These stick members, referred to as studs, wall plates and lintels (sometimes called headers), serve as a nailing base for all covering material and support the upper floor platforms, which provide the lateral strength along a
In the inner parts of a building, such beams are called "summers". It is part of the timber-frame construction in the overhanging upper story in jettying. [3] (UK) "Horizontal beam over a fireplace opening (alternatively lintel, mantel beam), or set forward from the lower part of a building to support a jettied wall, a jetty bressummer". [4]
Unusual sill framing in a granary of half-timber construction. Long tenons project through the sill plate. Timber sills can span gaps in a foundation. A sill plate or sole plate in construction and architecture is the bottom horizontal member of a wall or building to which vertical members are attached. The word "plate" is typically omitted in ...
