1. Which document is the primary referenced standard for masonry
construction in the IBC?
A. ACI 318
B. AISC 360
C. TMS 402/602
D. ASCE 7
Answer: C
The IBC adopts TMS 402 (design) and TMS 602 (specifications) as
the governing masonry standards.
2. The allowable stress design method for masonry is addressed in
which part of TMS 402?
A. Chapter 1
B. Chapter 2
C. Chapter 3
D. Chapter 4
Answer: C
, Chapter 3 of TMS 402 covers allowable stress design (ASD)
provisions.
3. Strength design provisions for masonry are found in:
A. TMS 402 Chapter 2
B. TMS 402 Chapter 4
C. TMS 602 Chapter 1
D. IBC Chapter 21
Answer: B
Chapter 4 of TMS 402 contains strength design (SD) requirements.
4. Which material property is used to determine the compressive
strength of masonry, f′m?
A. Mortar strength only
B. Unit strength or prism testing
C. Grout strength only
D. Steel yield strength
Answer: B
f′m is established using unit strength tables or prism tests, not
mortar alone.
5. What is the minimum nominal cover for reinforcing steel in
masonry exposed to earth?
A. 1/2 inch
B. 1 inch
C. 1 1/2 inches
D. 2 inches
Answer: D
Masonry reinforcing exposed to earth requires a minimum of 2
inches of cover.
,6. Which type of grout is typically used in masonry construction?
A. Structural lightweight grout only
B. Fine grout only
C. Coarse grout only
D. Fine or coarse grout
Answer: D
Both fine and coarse grout are permitted depending on cell size
and reinforcement.
7. What is the maximum height of masonry lift before grout
placement unless otherwise permitted?
A. 4 feet
B. 6 feet
C. 8 feet
D. 10 feet
Answer: C
Standard grout lift height is limited to 8 feet unless special
inspection allows more.
8. Masonry walls designed as load-bearing must meet which
minimum thickness requirement unless engineered otherwise?
A. 4 inches
B. 6 inches
C. 8 inches
D. 10 inches
Answer: C
Load-bearing masonry walls typically require a minimum nominal
thickness of 8 inches.
, 9. What type of inspection is required for masonry construction in
Seismic Design Categories D, E, and F?
A. Periodic inspection
B. Continuous inspection
C. No inspection
D. Owner inspection
Answer: B
High seismic categories require continuous special inspection for
masonry.
10. Which mortar type generally has the highest compressive
strength?
A. Type N
B. Type O
C. Type S
D. Type M
Answer: D
Type M mortar has the highest compressive strength among
common mortar types.
11. The purpose of horizontal reinforcement in masonry walls is
primarily to:
A. Increase compressive strength
B. Control cracking and resist tension
C. Support vertical loads
D. Improve thermal resistance
Answer: B
Horizontal reinforcement helps control shrinkage cracking and
resists tensile forces.
