Apr 23, 2023 · Cantilever beams are, after simply supported beams, the 2nd most used static system in structural engineering. There are plenty of cantilever beams in our daily lives, such as balconies, cranes or high-rise buildings. Calculating the internal and reaction forces due to loads is very easy because the static system is statically determinate. This ...
Oct 8, 2024 · A beam, in Structural Engineering terms, is a member that can be comprised of a number of materials (including steel and wood aluminum) to withstand loads – typically applied laterally to the beam axis. Beams can also be referred to as members, elements, rafters, shafts, or purlins. A beam can exist within a frame, a truss, or on its own as ...

- Simply Supported Beam. Starting from the simplest of the beams, the simply supported beam rests on a pin and roller support. Pin support allows rotation and roller support allow rotation and lateral movement.
- Overhanging Beam. Next we are looking at an overhanging beam in which some portion of the beam extends from the support from one side. The deflected shape of the beam on uniform loading between supports would look line white dashed line, in which both the supports will allow rotation of the beam.
- Fixed Beam. Next is, Fixed beam, which has fixed or rigid supports from both the ends. Deflected shape due to uniform loading will look something like white dashed line in which fixed supports will not rotate.
- Cantilever Beam. Next we will see a cantilever beam, which is fixed on one side and free on the other side. Deflected shape due to loading will look something like white dashed line.
Beam (structure) A statically determinate beam, bending (sagging) under a uniformly distributed load. 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 ...
In this lesson we'll explore beams. How is a beam different from and similar to elements that we've already studied? Where in a beam do shear, tension, and c...

A beam structure, at times essentially referred to as a beam, is a type of structure utilized in construction and development as well as engineering to provide a safe and productive load path that effectively distributes the weight all through the foundation of a building.
