What is the minimum width of a load-bearing CMU wall with filled cells?

• A. 6 inches
• B. 8 inches
• C. 10 inches
• D. 12 inches

Answer: (B)

The minimum width of a load-bearing Concrete Masonry Unit (CMU) wall with filled cells is 8 inches. This is a commonly accepted standard in construction and structural engineering practice. The reason for this minimum width is primarily based on the structural integrity and load-bearing capacity that is required for the wall to support vertical loads effectively. CMUs are designed to distribute loads over a larger area, and a wall with a minimum width of 8 inches ensures that there is sufficient material to handle the stresses imposed on it. Additionally, filled cells provide extra strength and stability, making the wall not only more capable of carrying loads but also more resilient against lateral forces, such as wind or seismic activity. Other widths mentioned may be used for specific applications or in specialized scenarios, but for typical load-bearing applications, 8 inches is the recognized minimum to ensure safety and adherence to building codes.
