Coastal and Floodplain Construction Inspector's Practice Exam

When is the attic considered an additional story for determining uplift and lateral bracing requirements?

1. When the roof slope is greater than 4 in 12

2. When the roof slope is greater than 5 in 12

3. When the roof slope is greater than 6 in 12

4. When the roof slope is greater than 7 in 12

The correct answer is: When the roof slope is greater than 6 in 12

The attic is considered an additional story for determining uplift and lateral bracing requirements when the roof slope exceeds 6 in 12. This specification is important because steeper roof slopes have an increased risk of wind uplift forces acting on the structure. When the roof pitch is more pronounced, it can create certain design challenges, leading to the need for enhanced bracing to ensure the stability and integrity of both the roof and the overall building. In structural design, including coastal and floodplain areas where exposure to wind and water effects is prevalent, determining the number of stories is crucial for ensuring that all lateral and uplift forces are properly accounted for in the design process. The additional requirements for uplift and lateral bracing help minimize the risks associated with both wind and water pressures. The specified slope threshold of 6 in 12 establishes a clear indicator for inspectors and builders regarding when these additional considerations must be incorporated in construction practices to comply with relevant codes and standards.
