Bridge Insp Definitions (NHI) || Get it Correct.
Abrasion correct answers The wearing or grinding away of material by water that contains sand,
gravel or stones.
Aggradation correct answers The general and progressive buildup of the longitudinal profile of a
channel bed due to sediment deposition
Air entrainment correct answers The process of forming minute air bubbles that are evenly
distributed throughout the concrete
Alkali silica reactivity (ASR) correct answers An expansive reaction that results in swelling and
expansion of concrete
Alloy correct answers A combination of two or more metals, or metal and another substance
Armoring countermeasures correct answers Devices that resist erosive forces caused by the flow,
but do not alter the flow direction
Axial force correct answers The force that acts through the longitudinal axis of a member.
Bending moment correct answers A combination of tension and compression forces developed
when an external load is applied transversely to a bridge member, causing it to bend.
Bridge elements correct answers Structural elements that are commonly used in highway bridge
construction and are encountered on bridge safety inspections.
Brittleness correct answers The ability of a material to break while exhibiting little to no plastic
deformation.
, Cantilever span correct answers A span with one end restrained against rotation and deflection
and the other end completely free.
Channel correct answers Typically well-defined and confines the streamflow during normal flow
conditions
Channel lining correct answers Rigid concrete pavement or flexible protective revetment mats
placed on the bottom of a streambed.
Checks correct answers Separations of the wood fibers, normally occurring across or through the
annual growth rings, and generally parallel to the grain direction
Chloride contamination correct answers The presence of recrystalized soluble salts, which causes
accelerated corrosion of the steel reinforcement
Collision damage correct answers A special case of overload that occurs when any vehicle,
railroad car, marine traffic or flowing ice strikes a bridge member, railing or column.
Continuous span correct answers A configuration in which a beam has one or more intermediate
supports and the behavior of the individual spans is dependent on its adjacent spans.
Contraction scour correct answers The removal of the material under the structure only.
Creep correct answers A gradual, continuing, irreversible deformation due to a constant stress
level below the yield strength
Crevice corrosion correct answers Occurs between adjacent surfaces but the rust may not
expand, even though significant section loss may have occurred
