Maximizing Support: Lateral Slide Show for Unsupported Beams

Explore the concept of lateral support in fully unsupported beams, where the unbraced length equals the member's total length. Discover how these beams, initially unsupported, get continual support from mechanically attached decks during construction. After joists are added, the unbraced length reduces to joist spacing. Beams act as crucial blocking elements for lateral support, essential for bending-loaded members. This lateral bracing, in various orientations including curved, is vital for construction stability.

  1. LATERAL SUPPORT SLIDE SHOW

  2. Fully unsupported beams. The unbraced length is equal to the entire length of the member.

  3. These beams are continually supported with the deck that is mechanically attached with screws or welds.

  4. These girders are fully unsupported temporarily during construction. Once the joists are placed in position and attached, the unbraced length is reduced to the joist spacing.

  5. Bracing is not only accomplished by joists. Here, beams are used as blocking and spaced to provide the necessary lateral support.

  6. Lateral bracing must be used for any member loaded in bending. It could be curved or in any orientation.
