Coastal and Floodplain Construction Inspector's Practice Exam

What is the purpose of the large missile test for glazed openings?

1. To measure thermal resistance

2. To ensure structural integrity against debris

3. To evaluate moisture resistance

4. To assess wind uplift resistance

The correct answer is: To ensure structural integrity against debris

The purpose of the large missile test for glazed openings is to ensure structural integrity against debris. This testing simulates the effects of impact from large pieces of flying debris that could occur during extreme weather events, such as hurricanes or tornadoes. The test is designed to determine how well the glazed openings—such as windows and doors—can withstand such impacts without breaking or failing, which is crucial for maintaining safety and integrity in coastal and floodplain environments. Other categories—like thermal resistance or moisture resistance—are not directly evaluated in this specific test. Although wind uplift resistance is significant in some structural assessments, it is not the primary focus of the large missile test. The main goal is to verify that the glazed openings will hold up under conditions where they might be struck by large, fast-moving objects, ensuring that structural safety standards are met in areas prone to high winds and debris impacts. This protective measure supports building resilience and safeguard occupants against the hazards posed by extreme weather conditions.
