If eight square feet of brick veneer wall need to be supported by anchor ties, how many ties are required (each tie supports 2 square feet)?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (C)

The idea is to match the total area to be supported with how much area one anchor tie can carry. If eight square feet must be supported and each tie covers two square feet, you determine the number of ties by dividing the total area by the per-tie capacity. Eight divided by two equals four, so you need four anchor ties to support the brick veneer wall. Using fewer would leave part of the wall unsupported, while using more would be extra—four is the exact, sufficient number.
