Bridge Inspection Study Guide and Practice Questions
The 3 major bridge components - correct answer ✔✔ Deck, Superstructure, Substructure
which is a permanent load? pedestrian, water, dead, or ice - correct answer ✔✔ Dead load
what is Axial Force? - correct answer ✔✔ a force that acts through the longitudinal axis of a
member
what is Strain? - correct answer ✔✔ measure of deformation which denotes the amount of
deformation with respect to the original dimension
Continuous Span - correct answer ✔✔ one or more adjacent spans and the behavior of each
span is dependent on its adjacent spans
load path redundancy - correct answer ✔✔ created by three or more main-supporting
members
pack rust - correct answer ✔✔ steel corrosion between mating surfaces of elements and results
in an increased volume of rust over the original steel
concrete is commonly used for what properties? - correct answer ✔✔ compressive strength
properties
in conventional reinforced concrete beams, which forces do the concrete and steel primarily
resist? - correct answer ✔✔ compression (concrete)
tension and shear (Steel)
, physical inspection methods such as hammer and drag chain may be used to detect which
concrete deficiency - correct answer ✔✔ delamination
which feature is responsible for the cross-grain strength of timber? - correct answer ✔✔ wood
rays
material with unique mechanical properties in atleast 2 of its principal axis of symmetry? -
correct answer ✔✔ Orthotropic
this situation requires specified conditions for air monitoring, standby attendees, a rescue plan,
and training - correct answer ✔✔ confined space entry
which inherent timber defect is a separation of the wood fibers parallel to the grain between
the annual growth rings? - correct answer ✔✔ Shakes
Beam - correct answer ✔✔ most common superstructure type, resists flexure and shear
type of bearing that provides for rotation but NOT for any longitudinal movement - correct
answer ✔✔ fixed bearing
which type of pier is often a narrow cylindrical or rectangular shaft that is supported by
INDIVIDUAL footings - correct answer ✔✔ column pier
represents the entire region beneath the bridge that is available to pass flood flows - correct
answer ✔✔ waterway area
which bridge inspection type establishes baseline structural conditions and potential problems -
correct answer ✔✔ initial inspection
