Coastal and Floodplain Construction Inspector's Practice Exam

What is the minimum embedment of bolts in concrete or masonry?

1. 5 inches

2. 7 inches

3. 9 inches

4. 10 inches

The correct answer is: 7 inches

The minimum embedment of bolts in concrete or masonry is typically established to ensure the structural integrity and load-bearing capacity of the connection. An embedment depth of 7 inches is generally recognized as sufficient for achieving adequate anchorage that allows the bolts to resist both tension and shear forces effectively. This depth helps to ensure that the concrete or masonry can provide the necessary friction and bonding to hold the bolt securely in place, while also accommodating potential shear loads that can occur in construction applications. In construction practices, factors such as the type of bolt being used, the load it will support, and the specific characteristics of the concrete or masonry may influence the required depth, but 7 inches is considered a sound standard for many typical applications. Other depths, such as those mentioned in the other options, may not be widely accepted or could be unnecessarily deep for common scenarios, thereby not aligning with established construction guidelines.
