According to code, what is the minimum required width of a footing in soil rated at 2000 PSF for a single-story building with 8 inch thick masonry walls?

• A. 12 inches
• B. 8 inches
• C. 16 inches
• D. 24 inches

Answer: (A)

To determine the minimum required width of a footing in soil rated at 2000 PSF for a single-story building with 8-inch thick masonry walls, one must consider the load distribution and the bearing capacity of the soil. In this context, the footings must be wide enough to effectively spread the load imposed by the walls over the soil, ensuring that the pressure on the soil does not exceed its allowable bearing capacity. When analyzing structural load, one typically looks at the weight of the masonry walls and translates that into the necessary footing width to prevent soil failure. The wall thickness contributes directly to the load that will be applied to the footing. With 8 inches of masonry, it naturally forms the base of the load spreading configuration. Generally, a footing width of at least 1.5 to 2 times the wall thickness is recommended, depending on the specific code requirements and safety factors considered. In this case, a minimum footing width of 12 inches, which is 1.5 times the wall thickness of 8 inches (equating to 12 inches), is designed to ensure a proper distribution of weight. This width provides a safe margin when interacting with the 2000 PSF bearing capacity of the soil, thus satisfying safety and structural
