When connecting a joist to a masonry wall, how deep must the bolt be embedded into the masonry wall at a minimum?

2 inches
3 inches
4 inches
6 inches

The correct answer is: 4 inches

When connecting a joist to a masonry wall, the requirement for a minimum bolt embedment depth is critical for ensuring structural integrity and stability. Embedding the bolt at least 4 inches into the masonry wall provides sufficient hold and load-bearing capacity, which is essential for securing the joist. The 4-inch embedment helps to ensure that the forces exerted on the connection are effectively transferred through the bolt into the masonry. This depth minimizes the risk of the bolt pulling out under heavy loads or shifting conditions. Furthermore, this standard also considers factors like the type of masonry and potential deterioration over time, ensuring that the connection remains secure throughout its use. In structural applications, complying with these embedment standards is crucial. The other options—2 inches, 3 inches, and 6 inches—do not meet the established minimum requirements or may be excessive without adding significant benefits in this context. Therefore, 4 inches is the minimum depth that strikes a balance between safety and feasibility for such connections.
