Question 2

An inspector observes diagonal tension cracks near the end of a reinforced concrete beam. What structural behavior is indicated?

Accepted Answer

Inadequate shear capacity near the support

Answer

Diagonal tension cracks at approximately 45 degrees near beam ends indicate shear stress exceeding the beam's shear capacity.

Question 3

What information is recorded in NBI Item 113 (Scour Critical Bridges)?

Accepted Answer

Whether the bridge is scour critical and the status of a scour action plan

Answer

NBI Item 113 codes indicate whether a bridge is scour critical and whether a required scour plan of action has been completed.

Question 4

A through-truss bridge has a gusset plate with visible out-of-plane distortion. What is the inspector's most critical next step?

Accepted Answer

Notify the bridge owner immediately and recommend an in-depth engineering evaluation

Answer

Gusset plate distortion in a truss is a potential sign of overload or buckling and requires immediate notification to the owner and an engineering evaluation.

Question 5

Which non-destructive evaluation (NDE) method is best suited for measuring the depth of corrosion-induced concrete cover loss without surface removal?

Accepted Answer

Ground penetrating radar (GPR)

Answer

GPR can detect rebar depth, delamination, and voids beneath the concrete surface without requiring surface removal.
