  2. Cantilever - Wikipedia

    en.wikipedia.org/wiki/Cantilever

    A cantilever in a traditionally timber framed building is called a jetty or forebay. In the southern United States, a historic barn type is the cantilever barn of log construction. Temporary cantilevers are often used in construction. The partially constructed structure creates a cantilever, but the completed structure does not act as a cantilever.

  3. Cantilever bridge - Wikipedia

    en.wikipedia.org/wiki/Cantilever_bridge

    A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers).For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete.

  4. Cantilever method - Wikipedia

    en.wikipedia.org/wiki/Cantilever_method

    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.

  5. Prestressed concrete - Wikipedia

    en.wikipedia.org/wiki/Prestressed_concrete

    Prestressed concrete is a highly versatile construction material as a result of it being an almost ideal combination of its two main constituents: high-strength steel, pre-stretched to allow its full strength to be easily realised; and modern concrete, pre-compressed to minimise cracking under tensile forces.

  6. Underpinning - Wikipedia

    en.wikipedia.org/wiki/Underpinning

    In construction or renovation, underpinning is the process of strengthening the foundation of an existing building or other structure. Underpinning may be necessary for a variety of reasons: The original foundation isn't strong or stable enough. The usage of the structure has changed.

  7. Jettying - Wikipedia

    en.wikipedia.org/wiki/Jettying

    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.

  8. Howrah Bridge - Wikipedia

    en.wikipedia.org/wiki/Howrah_Bridge

    It carries a daily traffic of approximately 100,000 vehicles [12] and possibly more than 150,000 pedestrians, [10] easily making it the busiest cantilever bridge in the world. [13] The third-longest cantilever bridge at the time of its construction, [14] the Howrah Bridge is currently the sixth-longest bridge of its type in the world. [15]

  9. Continuous truss bridge - Wikipedia

    en.wikipedia.org/wiki/Continuous_truss_bridge

    However, continuous truss bridges do not experience the tipping forces that a cantilever bridge must resist because the main span of a continuous truss bridge is supported at both ends. The result of collapse of a continuous truss bridge (the Francis Scott Key Bridge). It is possible to convert a series of simple truss spans into a continuous ...
