CCI Structural Inspection Methods 3

Question 1

Which destructive testing method is used to determine the actual yield strength of reinforcing steel from a completed structure?

Accepted Answer

Core sample testing with rebar extraction and tensile testing

Answer

Extracting rebar from a core sample and conducting tensile testing in a laboratory directly measures yield and ultimate strength of in-place reinforcing steel.

Question 2

A CCI inspector observes honeycombing in a formed concrete wall. What is the correct initial inspection action?

Accepted Answer

Document location and extent, then notify the engineer of record for evaluation

Answer

The inspector must document and report honeycombing to the engineer of record, who determines whether repair, testing, or removal is required.

Question 3

What does the term 'effective depth' mean in reinforced concrete beam design and inspection?

Accepted Answer

Distance from compression face to centroid of tension reinforcement

Answer

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.

Question 4

During wood-frame structural inspection, a 'cripple wall' refers to:

Accepted Answer

Short stud walls between the foundation and first floor framing

Answer

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.

Question 5

When inspecting a welded moment frame connection, what does 'complete joint penetration (CJP)' indicate?

Accepted Answer

The weld fuses completely through the full thickness of the base metal

Answer

A CJP weld penetrates and fuses the entire cross-section of the joint, providing full-strength connection required for moment frame performance.
