This document defines and describes different types of bridges, including beam, truss, cantilever, arch, suspension, and double-decked bridges. It then explains the key parts of a bridge, such as piles, pile caps, piers, transoms, girders, abutments, and deck slabs. Finally, it provides examples of bridges in Pakistan, including flyovers in Lahore and Rawalpindi as well as the longest bridge for a bus rapid transit system.

Bridges

4. Definition

that reason architects and engineers are making
bridges to satisfied those needs.

5. Types Of Bridges
Beam bridges
Truss bridges
Cantilever bridges
Arch bridges
Suspension bridges
Double-decked bridges

6. Beam Bridge
Beam bridges are horizontal
beams supported at each end
by substructure units. And
beams are connected across
two or more spans. When there
are multiple spans, the
intermediate supports are
known as piers.

7. Truss bridges
A Truss bridge is a
bridge whose load
bearing superstructure
is composed of a truss.
This truss is a
structure of connected
elements forming
triangular units.

8. Cantilever bridges
Cantilever
bridges are built
using cantilevers
horizontal beams
supported on only
one end.

9. Arch bridges
Arch
bridges have abu
tments at each
end. The weight
of the bridge is
thrust into
the abutments at
either side.

10. Suspension bridges
Suspension
bridges are
suspended
from cables.

11. Double-decked bridges
Double-decker bridges
have two levels, such
as a Double Decker
Bridge in Hong
Kong have six lanes on
their upper decks, and
on their lower decks
there are two lanes
and a pair of tracks
for MTR metro trains

structural beam
or bar on Pier
Of Bridge.
Transom

17. Girder
A girder is a
support beam used
in construction. Girde
rs often have an Ibeam cross
section for strength.
