Bridges Flashcards
(26 cards)
Beam
A ridged normally horizontal structure
Span
Distance a bridge extends between two supports
Caisson
A watertight area for workers to work during construction of bridge
Torsion
TWISTING
Abutment
The outermost end supports of a bridge which carry loads
Anchorage
A secure fixing usually made with reinforced concrete which cables are attached to
Reinforced concrete
Concrete with steal bars or mesh imbedded to increase strength
Tension
STRETCHING
Arch
A curved structure going downwards
Cable
A structural element formed from steal wire bound in strands
Compression
SQUEEZING
Pier
Vertical supporting structure such as a pillar
Truss
Triangles
Deck
Supported roadway on a bridge
Cantilever
A projecting structure with one side anchored at one end. ( diving board, porches)
Cast iron
Brittle alloy with high carbon content, iron that has been melted to help form new structures
Shear
RUB
Arch bridge
Natural strength, key stone, abutments, ancient
Beam bridge
Found over roadways, compression pushes down tension pushes up, piers to add strength
Cantilever/truss bridge
Triangles, very expensive, allow wind to come through
Suspension
Very expensive, truss system, the cables get tension which leads to compression in the towers, great span
Cable stay bridges
Form an “A”, cables attach to roadway, less expensive
Hangers
Connect cable to roadway
Dee bridge
Beam bridge, made with cast iron, for trains, failed
