Florida Building Code Practice Exam

What is the minimum thickness of masonry walls when constructed of solid masonry units?

1. 2 inches

2. 4 inches

3. 6 inches

4. 8 inches

The correct answer is: 4 inches

The minimum thickness of masonry walls constructed of solid masonry units is established to ensure structural integrity and adequate load-bearing capacity. For solid masonry units, the Florida Building Code specifies that the minimum thickness should be 4 inches. This thickness is necessary to accommodate various structural requirements, including wind loads and seismic considerations, while also allowing for proper bonding and stability of the masonry units. Thinner walls, such as those measuring 2 inches, would not provide the necessary strength and load distribution needed for typical building applications. A thickness of 6 inches, while more robust, exceeds the minimum requirement and might lead to unnecessary material use and increased costs. Similarly, an 8-inch wall offers additional strength but again goes beyond what is strictly required, which may not be efficient for most construction needs where 4 inches is sufficient.
