2. Introduction
- A bridge is a structure that permits you to cross over an obstacle.
- Suppose you lay a plank across a brook. You have a bridge. If the plank is thin in relation to its
length, it will sag. In fact, if it is too long, it will collapse. This shows that you must consider the
weight of a bridge itself---the “dead load”.
- If you stand at the middle of the plank, it sags even more. So, you must provide for the weight of
whatever your bridge is designed to carry---the “live load”.
- Also, when you walk across the plank, it bounces under you, illustrating the effect of a “moving live
load”.
- Finally, there is a “wind load”. A strong wind pushes against the sides, lifts the deck, shakes the
whole structure. Certainly the force of the wind is something to keep in mind.
- Bridges help us to connect to each other and the world.
- There are four main types of physical bridges. They are arch, beam, suspension and cable-stayed.

bridge

Junction, Ahmedabad

11. COMPONENTS OF BRIDGE
 Deck slab: It acts as a medium to bind the girders , as the load of vehivles is directly taken
by the deck slab & further transferred to girders.
 PSC Girders( prestressed concrete girder):girders are provided to give primary support to
the deck. In PSC girders the lower portion of the girder is prestressed to endure load
generated during a construction process such as slabbing or packing.
 Crash barrier : the barrier which checks errant vehicles from jumping outside from the
flyover is called as crash barrier/traffic barrier.
 Pedestal with bearing :pedestal is an independent support to bearings over pier. Bearing
used generally are pot bearing since they provide negligible vertical deflection and high
horizontal load carring capacity.
 Pier: It is a vertical supporting structure over pile cap is pier shaft.
 Pier cap: are usually made of concrete or hard stone , designed to distribute concentrated
loads evenly over the area of the pier.
 Pile :It is a column which transfers the load of superstructure directly to the soil strata.
 Pile cap: A thick concrete mat that rests on piles collectively to provide a suitable stable
foundation is pile cap.
