What is the minimum spacing requirement for wall ties in a masonry wall?

1. 2 feet

2. 4 feet

3. 3 feet

4. 5 feet

The correct answer is: 3 feet

The minimum spacing requirement for wall ties in a masonry wall is established to ensure structural integrity and adequate support for the masonry units. This particular spacing helps maintain the connection between the masonry and any backing materials, which is critical for transferring loads and providing stability against lateral pressures. In typical construction practices, spacing ties at every 3 feet is a common guideline that balances structural support with practical construction considerations. This distance allows for sufficient anchoring without overwhelming labor or materials, thereby promoting quality workmanship while also adhering to safety and performance standards. The incorrect options generally propose either too large or too small a spacing, which could compromise the overall strength and stability of the masonry wall. Spacing ties too far apart might lead to inadequate support and potential failure during stress events, while spacing them too closely could lead to unnecessary material costs and installation difficulties. Thus, the chosen spacing of 3 feet provides an optimal solution in masonry construction.
