Wind Loads On Roof Screens

Little research is currently available to provide guidance for determining wind loads on screen walls and equipment behind screens.

Wind loads on roof screens.

For very porous screens the loads are largely related to the action of wind as it flows through the screen. Wind load on surface wind load calculator. Wind loads on non standard buildings asce 7 10 wind. The roof screen sections are designed to handle approximately 100 mph winds 30 lbs.

The asce 7 16 commentary to section 29 5 1 suggests that the provisions for rooftop structures and equipment be used to generate wind forces on screen walls located away from the edge of a building. The study by kopp and traczuk 2007 provides the basis for the lateral and uplift wind force coefficients used in asce7 10 2010. Per square foot with minimal deflection. Therefore the screen mesh density is very important when determining the design wind loads of these structures.

Components cladding wind load provisions roofs walls 3. Table ah107 4 1 in appendix h of the 2006 irc table ah107 4 1 provides load cases wall and roof. Wind loads are important consideration in structural engineering in the design of a structure. Air curtains and air screens air curtains or air screens in open doorways are used to keep acceptable indoor comfort in buildings.

Wind tunnel applications for buildings 5. When building a structure it is important to calculate wind load to ensure that the structure can withstand high winds especially if the building is located in an area known for inclement weather. Basics of wind load provisions mwfrs s 2. But we have also custom designed screens as tall as 22 ft in higher wind areas.

Care should be taken to provide enough structural support for desired wind load ratings. We ve designed screens as high as 18 ft with our standard frame configurations in areas with relatively mild wind loads. Once these sections are mounted the screen appears as a continuous line of louvered equipment screen. And kopp and traczuk 2007.

Wind loads for signs other structures roof top structures equipment other special conditions 4. So the maximum reasonable height for a roof screen will be limited by the design wind pressure calculated for the project. Beaufort wind scale the beaufort description and observation of wind and. The code wind load provisions for roof mounted equipment in asce7 10 2010 are primarily based on wind loads obtained from model scale wind tunnel measurements by hosoya et al 2001.
