Study Notes

Beam Deflection

  • Beam deflection is the movement of a beam from its original position due to applied forces and loads.
  • Beams resist lateral loads. Columns resist axial loads.

Beam Definition

  • A beam is a structural element that resists loads applied laterally to its axis.

Deflection

  • Deflection is the degree to which a structural element, like a beam, deforms laterally under a load.
  • Bending moment is created by transverse loads, especially on cantilever beams.

Beam Curvature

  • Understanding beam curvature is central to comprehending beam bending.

Common Beam Materials

  • Wood, fiber glass, steel, and concrete are used in composite beams.
  • Concrete and steel composite beams can be used in various environments, including high-traffic areas.
  • Resin-based composite beams are better for durability, and are less disruptive to the natural landscape than traditional timber beams.

Moment-Area Method

  • The moment-area method uses the flexural rigidity diagram of a beam to determine deflection/slope.

Conjugate Beam Method

  • A conjugate beam is a fictitious beam with the same length as the actual beam.
  • It's used to determine the deflection and slope of the actual beam.

Buckling

  • Buckling is a change in structure geometry under compression, affecting load resistance.

Column Buckling

  • A column is a vertical member carrying compressive axial load.
  • Inelastic buckling is a type of column failure.

Torsional Buckling

  • Torsional buckling is a failure caused by twisting around a longitudinal axis.
