Coastal and Floodplain Construction Inspector's Practice Exam

Which of the following describes the required spacing for fasteners in the wall to foundation connection for a house located in a 100 mph wind zone?

1. 4 inches o.c.

2. 6 inches o.c.

3. 8 inches o.c.

4. 10 inches o.c.

The correct answer is: 6 inches o.c.

In a house located in a 100 mph wind zone, the required spacing for fasteners in the wall to foundation connection is typically 6 inches on center. This specification is crucial for ensuring the structural integrity and wind resistance of the building in regions prone to high winds. Fasteners are essential for securing various components together, and the specified spacing helps to distribute the loads effectively. In high wind zones, the force exerted on the structure can be significant, necessitating closer fastening intervals to prevent failure at the connections. The building codes and standards established for such conditions are designed to maximize safety and performance, aligning with the construction requirements for wind-resistant designs. The choices of 4 inches, 8 inches, and 10 inches on center either do not provide sufficient fastening strength or are unnecessarily excessive, potentially leading to inefficiencies in material use or installation complexity. Thus, 6 inches on center represents the optimal balance, supporting overall structural stability while adhering to best practices in construction for areas susceptible to high wind speeds.
