Coastal and Floodplain Construction Inspector's Practice Exam

In the 100 mph wind zone exposure B, what is the minimum diameter required for anchor bolts in wall to foundation connections?

1. 1/4 inch

2. 3/8 inch

3. 1/2 inch

4. 5/8 inch

The correct answer is: 1/2 inch

The minimum diameter required for anchor bolts in wall to foundation connections in a 100 mph wind zone exposure B is determined by structural engineering standards that account for the forces that buildings must withstand under high wind conditions. In exposure B, which generally includes buildings located in environments where structures may be subjected to significant lateral loads due to wind, a stronger connection between the wall and foundation is necessary to ensure stability and prevent failure. A diameter of 1/2 inch for anchor bolts provides the necessary strength and resilience to withstand such forces. Using a diameter of 1/2 inch ensures that the anchor bolts are adequately robust for use in structures facing significant wind loads, aligning with best practices established in building codes and engineering guidelines for coastal and flood-prone areas. This diameter also helps provide sufficient tension capacity to resist uplift and shear forces created by winds, ensuring the integrity of the connection under adverse weather conditions. The other options, while they may serve lesser load demands, do not meet the required structural strength for the specified wind zone, which is why they are not considered adequate for these connections.
