Basics of wind load provisions mwfrs s 2. The roof screen sections are designed to handle approximately 100 mph winds 30 lbs. For very porous screens the loads are largely related to the action of wind as it flows through the screen. Wind tunnel applications for buildings 5.

Therefore the screen mesh density is very important when determining the design wind loads of these structures. In order for a structure to be sound and secure the foundation roof and walls must be strong and wind resistant. Little research is currently available to provide guidance for determining wind loads on screen walls and equipment behind screens.
