  2. Double tee - Wikipedia

    en.wikipedia.org/wiki/Double_tee

    Diagram of double tee beam. A double tee or double-T beam is a load-bearing structure that resembles two T-beams connected to each other side by side. The strong bond of the flange (horizontal section) and the two webs (vertical members, also known as stems) creates a structure that is capable of withstanding high loads while having a long span.

  3. T-beam - Wikipedia

    en.wikipedia.org/wiki/T-beam

    A double-T beam or double tee beam is a load-bearing structure that resemble two T-beams connected to each other. Double tees are manufactured from prestressed concrete using pretensioning beds of about 200-foot (61 m) to 500-foot (150 m) long. The strong bond of the flange (horizontal section) and the two webs (vertical members) creates a ...

  4. Bearing capacity - Wikipedia

    en.wikipedia.org/wiki/Bearing_capacity

    The bearing capacity of soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil. Ultimate bearing capacity is the theoretical maximum pressure which can be supported without failure; allowable bearing capacity is the ultimate bearing capacity divided by a factor of ...

  5. I-beam - Wikipedia

    en.wikipedia.org/wiki/I-beam

    The designation for each is given as the approximate height of the beam, the type (beam or column) and then the unit metre rate (e.g., a 460UB67.1 is an approximately 460 mm (18.1 in) deep universal beam that weighs 67.1 kg/m (135 lb/yd)).

  6. Structural steel - Wikipedia

    en.wikipedia.org/wiki/Structural_steel

    A beam drill line (drill line) has long been considered an indispensable way to drill holes and mill slots into beams, channels and HSS elements. CNC beam drill lines are typically equipped with feed conveyors and position sensors to move the element into position for drilling, plus probing capability to determine the precise location where the ...

  7. Beam (structure) - Wikipedia

    en.wikipedia.org/wiki/Beam_(structure)

    A beam is a structural element that primarily resists loads applied laterally across the beam's axis (an element designed to carry a load pushing parallel to its axis would be a strut or column). Its mode of deflection is primarily by bending , as loads produce reaction forces at the beam's support points and internal bending moments , shear ...

  8. Structural support - Wikipedia

    en.wikipedia.org/wiki/Structural_support

    Whatever the condition is, a specific rigidity is necessary for connection designs. The support connection type has effects on the load bearing capacity of each element, which makes up a structural system. Each support condition influences the behaviour of the elements and therefore, the system.

  9. Structural engineering - Wikipedia

    en.wikipedia.org/wiki/Structural_engineering

    A beam may be defined as an element in which one dimension is much greater than the other two and the applied loads are usually normal to the main axis of the element. Beams and columns are called line elements and are often represented by simple lines in structural modeling. cantilevered (supported at one end only with a fixed connection)
