Coastal and Floodplain Construction Inspector's Practice Exam

What is the load resistance requirement for mullions supporting window and door assemblies?

1. 1.0 times the design pressure loads

2. 1.5 times the design pressure loads

3. 2.0 times the design pressure loads

4. 0.75 times the design pressure loads

The correct answer is: 1.5 times the design pressure loads

The correct choice regarding load resistance for mullions supporting window and door assemblies is to require 1.5 times the design pressure loads. This requirement is grounded in safety and structural integrity standards. By mandating that mullions can resist loads that are 1.5 times greater than the design pressure, it ensures a sufficient safety margin to accommodate potential overloads. This is critical in coastal and floodplain areas where environmental conditions can lead to significant forces acting on windows and doors, such as wind pressure, water pressure, or debris impact. Implementing this higher factor of safety not only provides extra support against unexpected increases in load but also accounts for uncertainties in material performance, installation variances, and the effects of environmental factors over time. This practice helps prevent structural failures that could result in property damage or safety hazards in extreme weather situations. Complying with this requirement is essential for meeting established building codes and ensuring the resilience of buildings in vulnerable locations.
