What Is A Beam?
A Beam is a horizontal structural element that
runs horizontally to withstand vertical
load coming off the building frame. The beam takes
the load & distributes it to ends and transfers it to columns, walls, and posts on both sides of the beam. it only
withstands laterally applied loads on the axis of the beam.
Types of Beam:-
1. Simply Supported Beam:
It is one of the simplest
structural elements that both ends rest on supports but is free to rotate. It
contains pinned support at one end and a roller support at the other end. Based
on the assigned load, it sustains shearing and bending.
2. Continuous
Beam:
A continuous beam is one that has two or more supports that
reinforce the beam. These supports are used under and between the beams and are
typically vertical in nature. Continuous beams are thought to be more
economical when compared to other beam types.
These types of beams
have more than one
span. A continuous beam is most commonly used in bridge construction. A beam of this type has more than two
supports along its length.
3. CANTILEVER BEAM:
A Cantilever Beam is a type of beam constrained
at one end with the other end extending freely outwards. In other words, this
beam is supported at one end and the other end is free i.e. it has no support.
In these types
of beams, the load coming on it transfers to the support where it can manage the moment of force and shear stress.
It is mostly used in car parking areas, construction of bridges, towers, etc.
4. Fixed Beam:
A fixed
beam is one that is fixed on both ends of the beam with supports. This type of
beam does not allow for bending moment production and will not have any
vertical movement or rotation. Fixed beams are most frequently used in trusses
and similar structures.
5. Overhanging Beam:
The overhanging
beam is one like a simply supported beam,
but it’s one end overhand or
extended from support to some distance.
Generally, every end of the beam is supported by
the column. In the case of an overhanging beam,
one end of a beam is supported by a column and
the other end is overhung without support.
Overhanging beams generally used to make shades or balconies, can vary from 40–120 cm in common residential buildings.
