  2. Laminated veneer lumber - Wikipedia

    en.wikipedia.org/wiki/Laminated_veneer_lumber

    LVL is a type of structural composite lumber, comparable to glued laminated timber (glulam) but with a higher allowable stress. [1] A high performance more sustainable alternative to lumber, Laminated Veneer Lumber (LVL) beams, headers and columns are used in structural applications to carry heavy loads with minimum weight.

  3. Grade beam - Wikipedia

    en.wikipedia.org/wiki/Grade_beam

    Grade beam. A grade beam or grade beam footing is a component of a building's foundation. It consists of a reinforced concrete beam that transmits the load from a bearing wall into spaced foundations such as pile caps or caissons. [1] It is used in conditions where the surface soil's load-bearing capacity is less than the anticipated design loads.

  4. Shear and moment diagram - Wikipedia

    en.wikipedia.org/wiki/Shear_and_moment_diagram

    Shear and Bending moment diagram for a simply supported beam with a concentrated load at mid-span. Shear force and bending moment diagrams are analytical tools used in conjunction with structural analysis to help perform structural design by determining the value of shear forces and bending moments at a given point of a structural element such as a beam.

  5. Lumber - Wikipedia

    en.wikipedia.org/wiki/Lumber

    Laminated veneer lumber (LVL) – LVL comes in 1 + 3 ⁄ 4-inch (44 mm) thicknesses with depths such as 9 + 1 ⁄ 2, 11 + 7 ⁄ 8, 14, 16, 18 and 24 inches (240, 300, 360, 410, 460 and 610 mm), and are often doubled or tripled up. They function as beams to provide support over large spans, such as removed support walls and garage door openings ...

  6. 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 ...

  7. 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.

  8. Euler–Bernoulli beam theory - Wikipedia

    en.wikipedia.org/wiki/Euler–Bernoulli_beam_theory

    Euler–Bernoulli beam theory (also known as engineer's beam theory or classical beam theory) [1] is a simplification of the linear theory of elasticity which provides a means of calculating the load-carrying and deflection characteristics of beams. It covers the case corresponding to small deflections of a beam that is subjected to lateral ...

  9. Four-point flexural test - Wikipedia

    en.wikipedia.org/wiki/Four-point_flexural_test

    The major difference being that with the addition of a fourth bearing the portion of the beam between the two loading points is put under maximum stress, as opposed to only the material right under the central bearing in the case of three-point bending.
