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. TYPES OF
BEAMS
●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.
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
