3. INTRODUCTION
DEFINATION:
Deflection –in engineering terms –is the degree to which an element
of structure changes shape when a load is applied. The change may
be a distance or an angle and can be either visible or invisible,
depending on the load intensity, the shape of the component and the
material from which it is made.

4. Slope & deflection
Slope: at any point on a beam, the angle made
By the tangent drawn to the deflected shope, with horizonatal is know as
slope at that point.
The unit of is radians or degree.
Deflection :-at my point, the vreetical distance betwwen the centreline of
original beam and the centreline of deflection beam as deflection at the
point.
Deflection is denoted by y.
The unit of deflection is mm.
In figure 6.1,
ABC = original beam
AC’B = deflected beam
Due to deflection of beam, point B comes to B’ position and point C
comes C’’ position.

5. TYPES OF DEFLECTION
Axial Deflection
Lateral Deflection
Angular Deflection
Combined Deflection
Torsional Deflection
Cyclic Deflection and Cycle Life
Pressure Balancing Examples
Hinged or Gimbalpipe Expansion Joints
Types of Metallic Bellows Deflection

6. TYPES OF DEFLECTION
PT&P offers all of the types of metal expansion joints. Each type has
advantages and limitations, which when applied correctly, can provide the
flexibility, load reduction, structural integrity and reliability desired in a
piping system.
Expansion joints, besides acting as sections of a pipe, capable of
withstanding the design temperatures, pressures, and media, also provide
the flexibility that makes them necessary. That flexibility can be either axial,
lateral or angular. However, in many installations, some rigidity or
structural strength is needed to support piping loads or to control the
motion of the bellows and the pipe. Features are then added to the
expansion joint to limit the modes or degrees of freedom, or the types of
deflections, and to resist shear, or tension, or compression loads and/or
bending moments. The most common types are presented in this catalog.

9. Beam deflection years of overloaded
strucuture

10. Deflection of reinforced concrete slabs is
acceptable to a certain limit which are specified
by applicable Codes such as ACI, IS Codes and
Euro Codes. These codes to specify the amount
of deflection which is acceptable.
