BRIDGE Flashcards
is a structure built to span physical obstacles without closing the way underneath such as a body of water, valley, or road for the purpose of providing passage over the obstacle.
Bridge
implies the provision of special structural elements that allow the suspension of humans and vehicles over the said obstacles.
“passage over”
refers to a tunnel
“passage under”
bridges over valleys or over other obstacles (other than rivers/body of water)
Viaduct
A bridge is a key element in a transportation system for three reasons:
- It is likely to controls the capacity
- It is the highest cost per kilometer
- If the bridge fails, the system fails.
the specialized structural engineering discipline of designing, constructing, and operating bridges.
Bridge Engineering
suspended structures require more careful considerations of loads and actions than those directly supported by the ground.
Designing
suspended structures are more complex to
construct than those directly supported by the ground.
Constructing
suspended structures are more hazardous to
operate than those directly supported by the ground
