4. BEAM DEFLECTION ANALYSIS
1.BEAM
 Beam is a horizontally structural member which carried load of slabs,
roofs etc.
2.DEFLECTION OF BEAM
 In engineering, deflection is the degree to which a structural element is
displaced under a load. It may refer to an angle or a distance.

5. 3.BEAM DEFLECTION ANALYSIS
 Beam analysis means to analyze/calculate the
deflection of beam at different load/supports.
For example:

6. Varying Deflection
 The deflection of beam can varies with varying the
loads/supports, because there analysis is different.
For example:
 supported at each end, concentrated load
deflection=-{load*( L)^3/( 48*E*I ) }
 supported at each end, uniformly distributed load
deflection= -{5*load*(L)^3/(384*E* I )}
 supported at one end, concentrated load at free end
deflection= -{load* (L)^3 /(3*E*I ) }
 supported at one end, distributed load
deflection=-{load*(length)^3 /(8*E*I)}

7. Where,
L= length of beam in (ft)
l= load acting on beam in (lb)
E*= elasticity in (lb/in^2)
I*= moment of inertia, in (in^4)
 E*=which is also known as the elastic modulus, It
defines the relationship between stress (force per unit
area) and strain (proportional deformation) in a
material.
The Young's modulus is a measure of the stiffness of a
solid material.
 I*=Is a geometrical property of an area which reflects
how its points are distributed with regard to an
arbitrary axis

8.  Working on beam is routine work of civil
engineering , because it is important structure
which mostly used everywhere.
 Beams can vary greatly in their geometry and
composition. For instance, a beam may be
straight or curved. It may be of constant cross
section, or it may taper. It may be made
entirely of the same material (homogeneous),
or it may be composed of different materials
(composite). Some of these things make
analysis difficult,

9. Analysis is simplified if:
 Only small deflections are considered (max
deflection less than 1/10 the span),
 Because the beams used for frame work are
selected on the basis of deflection, amongst
other factors. So small error make more
disaster therefore we merge exact formula in
program so error must be rectified, by doing
manually small error may be there such as:
We write 0.01 instead of 0.10( big error)

10.  To implement C++ language.
 To find out the exact deflection, because
Architects and engineers select materials for
various applications on the basis of deflection.
 To record the every data which we used.
 The detail of material etc.
 To have faster, easier and efficient system.
 To jump from manually to software
technology.

11. Software:
• Operating Windows
• RAM
• Processor
• Compiler (Code Block, Dev C++)
Hardware:
• Personal Computer
• Printer
• Hard disk

12.  Our program is on Dev c++ compiler.
 We use different types of header files such as:
#include <iostream> (for cout, cin etc,),
#include <math.h>(for mathematical expression),
#include <conio.h>(to get character ),
 Furthermore we use do while loop because it executes
at least one time may condition false.
It test the condition at the end.
 switch case statement tests the value of variable or
expression against a series of different cases or values,
until a match is found,
 If there are no matches found, the optional default case
is executed in the switch case statement.

17.  This project is very useful to those users which
face the difficulty for finding the deflection of
beam.
 This project gives more accurate result as
compares of manually doing.
