The document provides a comprehensive overview of bridges, defining them as rigid structures built to span an obstruction. It categorizes bridges based on various criteria such as their form, construction materials, and usage, detailing specific types including beam, truss, arch, and suspension bridges. Additional classifications include their movement capabilities, service period, and alignment in relation to the obstacle they cross.

1. Bridge
• Bridge is defined as a rigid structure that spans
horizontally between the supports built with a view
to provide a passage over an obstruction.
• The obstruction may be roadway, railway, river or
valley.
• The classification of bridges based on various
categories are briefly discussed in upcoming slides.

• Beam Bridge can be defined as a horizontal beam
which is supported at both the ends.
• This type of bridge may be simply supported or
continuous.

Cable Stayed
Bridge
• Truss is a structure of connected elements to form
triangular units.
• The bridge deck is supported by means of steel
trusses.
• This type of bridge is economical, efficient and is
most commonly used in railways.

Cable Stayed
Bridge
• The arch is located below the deck slab.
• The load on the deck slab is transferred to the arch
which in turn is transferred to the abutments (i.e.,
end supports).
• The abutment provided at each end of the arch
prevents the bridge from spreading out.

Suspension Bridge
Cable Stayed
Bridge
• It is similar to arch bridge but arch is positioned
above the bridge deck.
• The deck slab is supported by means of cables
which are suspended from the arch.

Suspension Bridge
Cable Stayed
Bridge
• Deck slab is supported by means of cables which are
attached to the suspenders, running on either side
of the bridge and throughout the length of the
bridge.
• The suspenders must be firmly anchored into the
ground.

Cable Stayed
Bridge
• It is similar to Suspension bridge but, the deck slab
is supported by the cables which are connected to
tall vertical towers called as pylons.
• The height of the pylon is much greater than that of
towers in suspension bridges

13. Types of Bridges
Continuous Bridge
Simply Supported
Bridge
Cantilever Bridge
Simply Supported Bridge is
similar to a simply
supported single span
beam which has supports
at its ends.
Bridge which is
continuous over more
than one span (i.e. bridge
spanning over more than
two supports).
It is similar to cantilever
beam which is fixed on one
end and the other end is
free.

18. THROUGH BRIDGE
The Bridge is constructed such
that its floor is at the bottom of
its superstructure.
SEMI-THROUGH
BRIDGE
The Bridge is constructed such
that its floor is provided in the
intermediate level of its
superstructure.
DECK BRIDGE
The Bridge is constructed such
that its floor is provided at the
top of superstructure.

Bridge
Submersible Bridge
Types of
Bridges
The super structure of the bridge is well below
the High Flood Level and so the bridge deck will
be submerged in water during the period of high
floods.
The super structure of the bridge is above the
High Flood Level and so the bridge deck will never
be submerged in water even during the periods of
heavy rain.
