Which destructive testing method is used to determine the actual yield strength of reinforcing steel from a completed structure?
Answer: Core sample testing with rebar extraction and tensile testing
Extracting rebar from a core sample and conducting tensile testing in a laboratory directly measures yield and ultimate strength of in-place reinforcing steel.
A CCI inspector observes honeycombing in a formed concrete wall. What is the correct initial inspection action?
Answer: Document location and extent, then notify the engineer of record for evaluation
The inspector must document and report honeycombing to the engineer of record, who determines whether repair, testing, or removal is required.
What does the term 'effective depth' mean in reinforced concrete beam design and inspection?
Answer: Distance from compression face to centroid of tension reinforcement
Effective depth (d) is the distance from the extreme compression fiber to the centroid of the tension steel, which determines the beam's moment arm.
During wood-frame structural inspection, a 'cripple wall' refers to:
Answer: Short stud walls between the foundation and first floor framing
Cripple walls are short stud walls between the foundation sill plate and the first floor, which are vulnerable to collapse in seismic events if not braced.
When inspecting a welded moment frame connection, what does 'complete joint penetration (CJP)' indicate?
Answer: The weld fuses completely through the full thickness of the base metal
A CJP weld penetrates and fuses the entire cross-section of the joint, providing full-strength connection required for moment frame performance.
What is the significance of the 'k-zone' in wide-flange steel sections during inspection?
Answer: The highly restrained area near beam-column flange/web intersection prone to weld cracking
The k-zone is a highly restrained area where the flange meets the fillet at the web, where weld heat-affected zone cracking has been a documented field problem.
An inspector is checking prestressed concrete hollow-core plank. End bearing length is critical because:
Answer: Too little bearing can cause plank end to kick off the support under load
If hollow-core plank does not have adequate bearing length on its support, the end can slide off and cause sudden structural collapse.
