– The supports where a bridge meets the ground.
Abutments resist the outward thrust (push) and
keep the bridge up.
• Arch bridge
– A type of bridge in which the compressive stress
created by the load is spread over the arch as a
• Cantilever bridge
– A type of bridge in which a beam is capable of
supporting a specified load at one end when the
opposite end is anchored or fixed.
– A squeezing force.
• Dynamic load
– A load on a structure that is always changing.
– The weight, mass, or force placed on a structure.
– A structure that extends from a bridge in the ground
below to form a firm foundation to support the
• Reinforced Concrete
– Concrete in which steel or plastic rods have been
embedded to increase the concrete’s resistance to
– A multidirectional sliding and separating force.
• Static load
– A load that is unchanging or that changes slowly.
– Cables that support a bridge deck from above.
– Something that encloses and defines a space; also, an
assembly of separate parts that is capable of
supporting a load.
– A rigid structural member that is in compression.
• Suspension bridge
– A bridge in which the deck is suspended (hung)
from hangers attached to a continuous cable,
which passes over towers and is anchored to the
ground at each end.
– A pulling force.
– A rigid structural member that is in tension.
– A structural element made up of a series of
