Coastal and Floodplain Construction Inspector's Practice Exam

How is uplift for the roof to wall connection determined when considering wind load?

1. Using soil pressure values

2. Evaluating local building codes

3. Assessing structure height

4. Based on wind speed and deadload

The correct answer is: Based on wind speed and deadload

In determining uplift for the roof-to-wall connection in the context of wind load, the primary factor is the wind speed and the dead load of the structure. Wind forces exert pressure on the building, which can cause the roof to be lifted away from the walls. The magnitude of uplift is directly related to the speed of the wind as it increases, necessitating an understanding of how wind pressures vary with different wind speeds. Dead load refers to the weight of the building's structural components, including the roof itself. This additional weight aids in counteracting the potential uplift caused by the wind. By taking into account both the anticipated wind speed and the dead load, inspectors and designers can assess the total forces acting on the roof-to-wall connection to ensure it is adequately designed to resist uplift. The other options, while relevant in the context of building design and safety, do not directly address the calculation of uplift for the roof-to-wall connection under wind loads. Soil pressure values are more aligned with foundation design, local building codes provide guidelines and requirements for construction practices but do not determine uplift specifically, and while structure height can influence overall wind pressures, it is not as critical as the immediate factors of wind speed and dead load in calculating uplift forces.
