While wind load calculations can be difficult to figure out because the wind is unpredictable, some standard calculations can give you a good idea of what a building can withstand. The State has amended the snow load requirements for determining required Snow Loads for their municipalities. The Peer-to-Peer Standards Exchange is a new ASCE Collaborate forum to discuss technical issues about ASCE standards. Broken windows, doors and garage doors can result in internal loads that amplify the forces and increase the risk of structural damage. JavaScript seems to be disabled in your browser.

On the surface the table for these structures appear to be different from that in ASCE 7; however, after some investigation we see that it yields identical pressures to ASCE 7-10. Tornadoes are common in North Louisiana and often embedded in hurricanes. For example, in the image below the circle is red because the building is NOT a simple diaphragm building and that is a requirement of the FBC alternative method.
