A beam is a structural element that primarily resist the loads applied to is laterally, these beams are known as structural beams. The complete effect of all the forces acting on the beam is to produce shear forces and bending moments to counter predict when breakages might occur, that in turn induce internal stress, strains and deflections on the beam. Beam are characterized in a few different ways, their manner of support, profile, shape of cross section, equilibrium conditions, length, and the material in which they are made of. Beams are typically descriptions of building or engineering structural elements. However, there are many other products that contain structural beams such as automobiles, aircrafts, machine frames, and other mechanical systems with heavy weight.
An I beam is the most efficient in one direction load bearing, if the I beam is bent side to side it functions as an H beam and is much less efficient. The most efficient shape for both directions in 2D is a box however the most efficient shape for bending in any direction is a cylindrical shell or tube. But, for unidirectional bending, the I or wide flange structural beam is superior. A H beam has a thicker center web which sometimes is misinterpreted as stronger but in reality, just has different applications.
Historically beams were squared timber sometimes having metal fasteners or being made of stone. Beams primarily carry vertical loads to act against gravitational forces. They are also used to carry horizontal loads to protect against an earthquake or wind or in tension to resist the rafter thrust as a tie beam. The loads carried by a structural beam are transferred to walls, columns, or girders, which in turn transfer the force to and adjacent structural compression member resulting in the force being transferred to the ground. Joists may be used in light frame construction that in turn rest on the beam itself.
You've saved our business! I beam is worth much more than I paid. It fits our needs perfectly. I couldn't have asked for more than this
