What is beam?
Beam:
Any structural compressive member, whose cross-section
is much smaller compare to it’s length and which can carry
vertical, shear and horizontal load (carries loads transversely,
that is, perpendicular to its long axis) is called Beam
types of beam?
According to Equilibrium Condition Two types beam.
According to End Support Condition six type of beam.
Statically Determinate beams (if the support reaction can be found by
using basic equilibrium equations, they are statically determinate)
1. Simply supported beam
2. Overhanging beam
3. Cantilever beam
Statically indeterminate beams (if the support reaction can not be
found by using basic equilibrium equations , they are statically
indeterminate)
1. Continuous Beam
2. Fixed beam
3. Beam fixed at one end and simply supported at the other end or
Propped Cantilever beam
What is beam deflection?
Beam deflection refers to the displacement of a structural member
when subjected to loads, such as point load, distribution loads.
Depends : the amount of deflection depends on
1. the beam material properties ,
2. cross-sectional geometry,
4. length and
4. type of load applied .
Effects of Deflection:
1. Structural instability.
2. Functional and alignment issues.
3. Material fatigue concerns.
4. Amplified vibrations under dynamic loads.

1. What is column?
A vertical structural member subjected to an axial compressive force is
called a column. The cross– sectional dimensions of column are large.
Normally, columns carry heavy compressive loads
What is STRUT?
A structural member subjected to an axial compressive force is called
strut. Strut may be vertical, horizontal or inclined. The cross– sectional
dimensions of strut are small. Normally, struts carry smaller
compressive loads.
Difference between beam and column?
2. Types of column?
3. Types of column about end condition?
1.Both end hinged.
2.Both end fixed.
3.One end fixed and other hinged.
4.One end fixed and other free.
4.BUCKLING LOAD/CRITICAL LOAD?
The minimum axial load at which the
column just begins to bending or buckle is called
buckling load. It also called Crippting load.
5. what is Slenderness ratio?
The ratio of the effective length of a column to the least radius of
gyration the column is known as slenderness ratio.
6. What is slender column?
A slender column" is a structural member, that has a significantly
greater height compared to its cross-sectional dimensions.
