1. BRIDGES
Assist. Prof. Dr. Güven KIYMAZ

2. A bridge is a structure built to span a valley, road,
railroad track, river, body of water, or any other
physical obstacle.
A wooden bridge used to cross over a river

3. The first bridges made by humans were probably
spans of wooden logs or planks and eventually
stones, using a simple support and crossbeam
arrangement.

4. A bridge can be designed for
•Trains,
•Road traffic,
•Pedestrian,
•A pipeline,
•Barge traffic,
•An aqueduct
Classification of bridges by use

•suspension bridges,
•cable-stayed bridges
Classification of bridges by structural system

14. Beam Bridge
•is similar to the log bridge,
•is now made from steel 'I' beams, box girders,
reinforced concrete, or post-tensioned concrete.
•is frequently used in pedestrian bridges and for
highway overpasses
•is in structural terms the simplest of the many
bridge types.
•consist of one or more horizontal beams with 2
supports usually on either end.

17. Cantilever bridge
•is a bridge built using cantilevers: structures that
project horizontally into space, supported on only
one end.
•A simple cantilever span is formed by two
cantilever arms extending from opposite sides of
the obstacle to be crossed, meeting at the center

21. Arch bridge
An arch bridge is a semicircular structure with
abutments on each end. The design of the arch, the
semicircle, naturally diverts the weight from the
bridge deck to the abutments.

22. Types of Arch Bridges
Hingless arch bridge Two-hinged arch bridge
Three-hinged arch bridge Tied arch bridge

35. Truss bridge
•A truss bridge is a bridge composed of connected elements
(typically straight) which may be subjected to tension,
compression, or sometimes both in response to dynamic loads.
•Truss bridges are one of the oldest types of modern bridges
•Truss type of bridge structure has a fairly simple design and
is particularly cheap to construct owing to its efficient use of
materials.

36. There are several types of truss bridges such as:
•Baltimore truss
•Bollman truss
•Bowstring arch truss (tied arch)
•Cantilevered truss
•Fink truss
•Howe truss
•Lenticular truss
•Pratt truss
•Warren (non-polar) truss

39. Ballman type truss bridge

40. Bowstring type truss bridge

41. Brown type truss bridge
This type of truss is particularly suited for
timber structures that use steel rods as
tension members

42. Howe type truss bridge

43. Pratt type truss bridge
(The opposite of Howe type truss)

44. Pratt type truss bridge

45. Warren type (non-polar) truss bridge

49. Suspension Bridges
A suspension bridge is a type of bridge where the
main load-carrying elements are hung from
suspension cables. Suspension bridges have two tall
towers through which the cables are strung.

66. Cable stayed bridges
A cable-stayed bridge is a bridge that consists of one
or more columns (normally referred to as towers or
pylons), with cables supporting the bridge deck.

67. There are two major classes of cable-stayed bridges, differentiated
by how the cables are connected to the tower(s).
• In a harp design, the cables are made nearly parallel
• In a fan design, the cables all connect to or pass over the top
of the tower.
