2. Structural channel - Wikipedia

   en.wikipedia.org/wiki/Structural_channel

   The structural channel is not used as much in construction as symmetrical beams, in part because its bending axis is not centered on the width of the flanges. If a load is applied equally across its top, the beam will tend to twist away from the web. This may not be a weak point or problem for a particular design, but is a factor to be ...

3. Deck (bridge) - Wikipedia

   en.wikipedia.org/wiki/Deck_(bridge)

   Structural engineers have several principal categories of bridge decks, for the purposes of analytic techniques. A beam deck is one where the deck and any supporting structure act together as a single beam. A grid deck uses beams and diaphragms as the supporting structure. The supporting system of a grid deck is analyzed using a grillage analysis.

4. 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.

5. Girder bridge - Wikipedia

   en.wikipedia.org/wiki/Girder_bridge

   The term "girder" is typically used to refer to a steel beam. In a beam or girder bridge, the beams themselves are the primary support for the deck, and are responsible for transferring the load down to the foundation. Material type, shape, and weight all affect how much weight a beam can hold.

6. Glossary of structural engineering - Wikipedia

   en.wikipedia.org/wiki/Glossary_of_structural...

   The loads applied to the beam result in reaction forces at the beam's support points. The total effect of all the forces acting on the beam is to produce shear forces and bending moments within the beam, that in turn induce internal stresses, strains and deflections of the beam. Beams are characterized by their manner of support, profile (shape ...

9. 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 ...
