This document discusses different types of beams and beam reactions. It defines a beam as a structural element that resists bending loads. The main types of beams described are simply supported, fixed, cantilever, overhanging, continuous, and trussed beams. Simply supported beams are supported at the ends and free to rotate, while fixed beams are restrained from rotating. Cantilever beams are fixed at one end only. The document also discusses types of beam loads and reactions, noting that reactions depend on the beam type, loads applied, and support type. Reactions always occur at support ends for any applied forces or couples.

2. BEAMWhat is a beam ?
A beam is a structural element that is
capable of withstanding load
primarily by resisting bending.And
is the horizontal member of a
structure, carrying transverse loads

3. ● Simply supported - a beam supported on the ends which are free to
rotate and have no moment resistance.
● Fixed - a beam supported on both ends and restrained from rotation.
● Over hanging - a simple beam extending beyond its support on one
end.
● Continuous - a beam extending over more than two supports.
● Cantilever - a projecting beam fixed only at one end.
● Trussed - a beam strengthened by adding a cable or rod to form a
truss. http://alltypeim.blogspot.in/

4. SIMPLY SUPPORTED
BEAM
It is a beam supported freely at the two
ends on walls or columns. In actual
practice, no beam rests freely on the
supports (walls or columns).

5. FIXED BEAM
In this beam, both ends of the beam are
rigidly fixed into the supports. Also,
Main reinforcement bars and stirrups
are provided.

6. CANTILEVER BEAM
A cantilever is a beam anchored at only one
end. The beam carries the load to the support
where it is forced against by a moment and
shear stress

7. OVERHANGING
BEAM
In overhanging beam, Its end extends
beyond the wall or column support.
Overhanging of the beam is the
unsupported portion of the beam. It may
be one side or both the sides of the
support.

8. CONTINOUS BEAM
A continuous beam is a statically indeterminate
multispan beam on hinged support. The end spans may
be cantilever, may be freely supported or fixed
supported.

9. TRUSS BEAM
A beam reinforced by a truss rod or
formed of straight or cambered pieces
joined by trussing

12. REACTION IN BEAMS
● THE REACTION IN BEAM DEPENDS ON THE TYPE OF
BEAM AND TYPE OF LOAD ON BEAM AND EVEN ON THE
TYPE OF SUPPORT .
SOME BASIC TYPES OF REACTIONS ARE :
The reaction at the support on application of UDL,UVL,force and
couple

13. REACTION IN
BEAMS
●
Reaction is always generated at ends of
support whether be it force or be a
couple
