APPLICATIONS OF DIFFERENT TYPES OF BEAMS AND GIRDERS

1. APPLICATIONS OF DIFFERENT
TYPES OF BEAMS AND GIRDERS

2. STEEL BEAMS

3. Steel beams are extremely crucial and necessary
for the construction any building or structure,
such as bridges, etc. They come in a wide range
of sizes and shapes.

5. I-Beam:
● These steel beams are shaped like
the capital letter ‘I’. They are
commonly used in industrial
applications and have tapered
flanges. I-shaped cross-section
steel beams come in two different
styles, one has a parallel flange
surface (wide), whereas the other
one has a slope on the inner flange
surfaces (S-beam).

6. W-Beam:
● These are similar to I-beams and
they are also called as ‘wide flange’
beams. They have a straight flange
and are most often used in
residential construction.

7. H-Beam:
● These are generally heavier and
longer than I-beams. Appearing like
the capital letter ‘H’, they have
longer flanges. Often, the term is
interchangeably used with I-beams,
so this can be confusing at times.
H-beams have webs and flanges
that have the same thickness in
many cases.

8. Channels:
● Like one half of the I-beam, these
have a C-shaped cross-section. The
top and bottom part of the beam
have sloped inner flange surfaces
that come out only on one side of
the beam. They are used in
supporting lighter loads since they
are not as strong as the other
beam shapes.

9. Curved beam:
● Beam with curved profile, such as
in the case of circular buildings.

10. Castellated beam
A castellated beam is a beam style where an
I-beam is subjected to a longitudinal cut
along its web following a specific pattern.
The purpose is to divide and reassemble
the beam with a deeper web by taking
advantage of the cutting pattern.
● used in the construction of bridges
● It is used in the construction of dams
● Used in the construction of high-rise
structures.

11. BUILT - UP BEAMS
● The use of cold-formed steel members
has increased in recent years,
especially in light-weight steel
construction, such as steel-framed
housing, low-rise office buildings,
factories, and warehouses due to its
high strength to weight ratio. Cold
formed steel built-up sections are
commonly used as compression
members to carry heavier loads and
over longer spans when a single
individual section is insufficient.

12. GIRDERS

13. Steel girders are a type of steel beams. Girders
are collector beams, they are the main horizontal
supports of a structure which support the smaller
beams. So “all girders are beams but all beams
are not girders”. Steel girders and beams differ
from each other in various aspects.

14. Girders have high load bearing capability. They
can withstand heavy loads as steel is highly
durable. They are responsible for the support
function of any structure. Girders carry ‘dynamic
loads’ and ‘rolling loads’. This is typical of steel
girders. Due to its high load bearing capability
steel girders are widely used in the construction
industry.

15. The main function of a steel girder is to transfer the load to
the columns on which it rests. A steel beam transfers load
to the steel girder. This is another key distinguishing factor
between a steel girder and a steel beam. Girders are often
used for constructing bridges.

17. Plate girders
Plate girders are usually used to construct
bridges that are suitable for short to
medium spans andmay support railroads,
highways, or other traffic.
Some of the most commonly used girder
bridges are:
● Box Girder Bridge
● Beam Bridge
● Multi- Girder Composite Bridges
● Half-Through Plate Girder Bridges

18. lattice girders
● The use of lattice girders should be
considered for projects where
shotcrete will be used for temporary
or permanent support. These
include mining through soft ground,
mixed face and rock, or tunnels in
which widths or heights may vary.
Lattice girders are applied equally
well to circular and horseshoe
shaped excavations, whether driven
full face or heading and bench.

19. Warren girder
● Warren girder contains a series of
isosceles triangles or equilateral
triangles. To increase the span
length of the truss bridge,
verticals are added for Warren
girder.

20. Gantry girders
● Gantry girders are used in the
factories, where the loads are
transferred from one place to
another with the helps of cranes
mounted on the bridges. Bridges
across the yards are supported
by the gantry girders with the
help of the wheels and rails on the
girders.
