Sample AZ ROC A-11 Steel & Aluminum Erection Practice Questions

Try these sample questions to review concepts for the AZ ROC A-11 Steel & Aluminum Erection exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1According to AISC specifications, what is the specified minimum yield strength (Fy) and minimum tensile strength (Fu) for standard ASTM A992 wide-flange (W-shape) structural steel members?

A.Fy = 50 ksi; Fu = 65 ksi

B.Fy = 36 ksi; Fu = 58 ksi

C.Fy = 46 ksi; Fu = 60 ksi

D.Fy = 70 ksi; Fu = 90 ksi

Explanation: ASTM A992 is the standard steel grade for structural wide-flange shapes (W-shapes). It specifies a minimum yield strength (Fy) of 50 ksi and a minimum tensile strength (Fu) of 65 ksi, with a maximum yield-to-tensile ratio of 0.85.

2An ironworker crew is hoisting a carbon steel base plate measuring 5 feet wide, 10 feet long, and 3/4 inch thick. Using the standard steel density rule of 490 lbs/cu ft (40.8 lbs/sq ft per inch of thickness), what is the total calculated weight of this plate?

A.1,020 lbs

B.1,530 lbs

C.1,275 lbs

D.2,040 lbs

Explanation: Steel plate weight is calculated using 40.8 lbs per square foot per inch of thickness. Plate area = 5 ft x 10 ft = 50 sq ft. Weight per sq ft for 3/4" (0.75") = 50 sq ft x (40.8 lbs/sq ft/in x 0.75 in) = 50 x 30.6 = 1,530 lbs.

3A structural detail drawing specifies a beam section labeled 'W14x90'. What do the numbers '14' and '90' designate in standard AISC nomenclature?

A.Nominal flange width of 14 inches and nominal depth of 90 inches

B.Nominal web thickness of 0.14 inches and yield strength of 90 ksi

C.Nominal depth of 14 inches and nominal weight of 90 pounds per linear foot

D.Nominal length of 14 feet and total weight capacity of 90 kips

Explanation: In AISC W-shape nomenclature, the letter 'W' indicates a wide-flange shape, the first number ('14') represents the nominal section depth in inches, and the second number ('90') represents the nominal weight in pounds per linear foot.

4Which structural aluminum alloy temper is most commonly used for extruded structural framing members, angles, and channels due to its high strength and good corrosion resistance?

A.3003-H14

B.5052-H32

C.7075-O

D.6061-T6

Explanation: 6061-T6 is the standard structural aluminum alloy for extruded shapes, plates, and structural framing. It is solution heat treated and artificially aged, providing a minimum yield strength of 35 ksi and excellent structural performance.

5A 100-foot-long structural steel bridge girder is installed at 40°F. During peak summer heating, the steel temperature rises to 100°F. Given the coefficient of thermal expansion for structural steel is 6.5 x 10^-6 in/in/°F, how much will the girder expand in length?

A.0.468 inches

B.0.234 inches

C.0.936 inches

D.1.250 inches

Explanation: Thermal expansion ΔL = L0 x α x ΔT. L0 = 100 ft x 12 in/ft = 1,200 inches. ΔT = 100°F - 40°F = 60°F. ΔL = 1,200 in x (6.5 x 10^-6 in/in/°F) x 60°F = 0.468 inches.

6When attaching structural aluminum framing members directly to structural carbon steel supports in an exterior environment, what precaution must be taken to prevent galvanic corrosion?

A.Flame-treat the contact surfaces prior to mechanical fastening

B.Isolate the metals using non-conductive dielectric gaskets, elastomeric washers, or alkali-resistant coatings

C.Use un-coated copper fasteners to ground the joint assembly

D.Increase the tightening torque of carbon steel bolts by 50%

Explanation: Galvanic corrosion occurs when dissimilar metals (aluminum and carbon steel) touch in the presence of an electrolyte (moisture). Non-conductive dielectric isolation materials, such as neoprene gaskets, fluoropolymer washers, or bituminous/chromate coatings, break electrical contact and prevent rapid aluminum oxidation.

7What does the designation '24K8' indicate for an Open Web Steel Joist manufactured under Steel Joist Institute (SJI) specifications?

A.24-inch chord width and 8-kip total point load capacity

B.24-foot maximum span length and 8 gauge top chord steel thickness

C.24-inch overall joist depth and section number 8 (design load designation)

D.24-inch bearing seat depth and 8-inch web angle spacing

Explanation: In SJI K-series joist designations (e.g., 24K8), the first number ('24') designates the nominal joist depth in inches, 'K' indicates K-series open web steel joists, and the trailing number ('8') designates the specific chord and web section number.

8What is the primary structural purpose of installing headed shear stud connectors through metal deck onto structural steel floor beams?

A.To hold temporary perimeter safety net brackets during erection

B.To allow thermal contraction of the concrete deck without cracking

C.To ground the metal floor deck against lightning strikes

D.To transfer horizontal shear forces and create composite action between the concrete slab and steel beam

Explanation: Headed shear studs welded through metal deck to the top flange of steel beams transfer horizontal shear forces between the hardened concrete slab and the steel beam, causing them to act together as a single composite structural unit.

9How does the weight density of structural aluminum compare approximately to the weight density of structural carbon steel?

A.Aluminum is approximately 1/3 the weight of structural steel

B.Aluminum is approximately 1/2 the weight of structural steel

C.Aluminum is approximately equal in weight to structural steel

D.Aluminum is approximately 1.5 times heavier than structural steel

Explanation: Structural steel has a density of approximately 0.283 lbs/cu in (490 lbs/cu ft), whereas structural aluminum (6061 alloy) has a density of approximately 0.098 lbs/cu in (169 lbs/cu ft). Thus, aluminum weighs roughly one-third (35%) as much as steel for an equal volume.

10According to ASTM specifications, what is the specified minimum yield strength for cold-formed welded structural tubing designated as ASTM A500 Grade B (Shaped)?

A.36 ksi

B.46 ksi

C.50 ksi

D.65 ksi

Explanation: ASTM A500 Grade B square and rectangular structural tubing (HSS) has a specified minimum yield strength of 46 ksi (and minimum tensile strength of 58 ksi). Note: Grade C provides 50 ksi yield strength.
