6. DEFINITION
A bridge is a man-made structure
built to avoid physical obstacles
without closing the way
underneath such as a body of
water, valley, or road.

9. A bridge is a man-made structure built to avoid
physical obstacles without closing the way
underneath such as a body of water, valley, or
road. It is constructed for the purpose of
providing passage over the obstacle. The first
bridges made by humans were probably spans of
cut wooden logs or planks and eventually stones,
using a simple support and crossbeam
arrangement.
INTRODUCTION

10. MAJOR PARTS OF BRIDGE
Every bridge can be divided broadly into three parts:
1.Superstructure
2.Substructure
3.Foundation.

11. SUPERSTRUCTURE
Superstructure that part of the
structure which supports traffic and
includes deck, slab and girders. All
the parts of the bridge which is
mounted on a supporting system can
be classified as a Super structure.

12. Substructure that part of the
structure, ie piers and abutments,
which supports the superstructure
and which transfers the structural
load to the foundations.
SUBSTRUCTURE

13. FOUNDATION
Foundation is the component which
transfers loads from the substructure to
the bearing strata.
Depending on the geotechnical
properties of the bearing strata, shallow
or deep foundations are adopted.
Usually, piles and well foundations are
adopted for bridge foundations.

14. The distance between two
bridge supports, whether they
are columns, towers or the
wall of a canyon.
SPAN

15. DECK
Deck is bridge floor directly
carrying traffic loads.
Deck transfers loads to the
Girders depending on the
decking material.

16. BEAM
Beam is a rigid, usually
horizontal, structural
element.

18. An arch bridge is a
bridge with abutments
at each end shaped as
a curved arch.
