1. A PRESENTAION ON :
BEAM SUPPORT AND
REACTION

2. BEAM
What 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. TYPES OF
BEAMS
Simply supported -
a beam supported
on the ends which
are free to rotate and
have no moment

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

10. TYPES OF
SUPPORT

11. TYPES OF LOADS

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
