Rajkiya Engineering College, Bijnor presented information on bridge engineering. Bridges are key infrastructure that allow crossing of obstacles like rivers and canals. A bridge consists of substructure elements like foundations, piers, and abutments, and superstructure elements like the deck. Bridges are classified by span length, material used, and the type of superstructure. Bridges improve transportation, emergency response times, and reduce traffic congestion. Selection of a bridge type depends on site conditions, traffic needs, structural requirements, and material availability.

Bridge Engineering

2. Introduction To Bridge
Engineering
Bridge is a KEY ELEMENT in a
Transportation System

3. DEFINITION
A bridge is
structure that
allows people or
vehicles to cross an
obstacle such as
river or canal or
railway….

4. Substructure
2. Pier (Column)
3. Abutment
Superstructure
1. Foundation
(Pile/Spread footing)
1. Any above bearing Structure
2. Wearing surface

5. Components Of Bridge

6. Definition of Components of
bridge
Deck
A bridge with an
upper horizontal
beam that carries
roadway.

7. Abutment
It supports the ends of
the bridge and transfer
the loads from the
superstructure into the
ground.

8. PIERS
The main supports
for a bridge upon
which the bridge
rests are
called piers.

9. Bearing
A bridge bearing is
a component of a
bridge which
typically provides a
resting surface
between bridge
piers and the bridge
deck.

24. IMPORTANCE OF BRIDGES
Improvement of environment for
emergency care.
Improvement of convenience of public
transportation.
Ease of traffic jam and reduction of
railroad crossing.

25. Improvement of environment for
emergency

26. Improvement of
convenience of public
transportation

27. Ease a traffic jam and reduction of a railroad
crossing

28. GENERAL DATA COLLECTION
location of bridge site.
Transportation of bridge site.
Nature of crossing and affordability.
Availability of local material.
Traffic volume.
Availability of local bridge builders.
Temporary crossing.
Local participation.

29. VERTICAL
CLEARANCE
Minimum vertical clearance of
5m should be ensure over the full
width of roadway.
 The vertical clearance should
be measured with regard to the
highest point of carriageway.
Allowance for any future raising
of pavement is also be made.

30. a) Geometric condition of the site(road alignment, design
flood and highest water mark)
b) Traffic capacity.
c) Structural stability.
d) Foundation conditions and strength of a abutment.
e) Available material.
f) Knowledge and equipment of the contractor.
g) Clearance requirement above and below the road way.
h) General requirements with respect to location ,financing
and community values.

BRIDGE TYPE
