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.
