Final answer:
The recommended deflection criteria due to wind loading on a brick veneer wall with a metal stud back up system depends on factors such as wall height and allowable bending moment. Generally, a common deflection criteria is that the maximum deflection should not exceed L/120, where L is the wall height.
Step-by-step explanation:
The recommended deflection criteria due to wind loading on a brick veneer wall that utilizes a metal stud back up system depends on the specific building code and design requirements. Generally, the deflection criteria for wind loading on such walls is governed by factors such as the height of the wall, the type of construction, and the allowable bending moment of the metal studs.
For example, one common deflection criteria is that the maximum deflection of the wall should not exceed L/120, where L is the height of the wall. This criteria ensures that the wall remains structurally stable and does not crack or fail under wind loading.
It is important to consult the applicable building code or a structural engineer to determine the specific deflection criteria for your situation, as they may vary depending on the location and specific requirements.
