Coastal and Floodplain Construction Inspector's Practice Exam

Which fasteners are recommended for gable end walls in buildings with a design wind speed of 100 mph or greater?

1. 8d common or 10d common

2. 8d common or 8d hot dipped galvanized

3. 6d ordinary or 8d hot dipped galvanized

4. 10d steel or 8d common

The correct answer is: 8d common or 8d hot dipped galvanized

When constructing gable end walls in areas subject to high wind speeds, such as those specified for a design wind speed of 100 mph or greater, it's essential to select fasteners that provide adequate structural integrity and resistance to corrosion. Hot dipped galvanized fasteners are particularly recommended because they have a protective coating that not only enhances their durability but also provides resistance to the elements, which is crucial in coastal and high-wind environments. The choice of using 8d hot dipped galvanized fasteners helps ensure that they can withstand the lateral forces imposed by high winds without failing. These fasteners are sufficiently robust and, due to their size, create strong connections in the framing of the gable end wall. In contrast, using regular steel or ordinary fasteners without a protective coating may lead to rust and failure over time, especially in marine or flood-prone areas. The emphasis on hot dipped galvanized fasteners in situations with elevated design wind speeds reflects a commitment to ensuring safety and structural adequacy in building practices subject to extreme weather conditions.
