Now whether or not this case will ever control is something you would have to determine.
In that case, even though you have side wall pressures that are equal and opposite in direction, the MWFRS will only see one of the side wall pressures and have a force exerted on it. You treat this force the same as you would on a floor diaphragm with respect to Figure 6-9.Īs to part 2, I have never included side wall pressures in calcs unless you have a building with an expansion joint. Bart Quimby, P.E., F.ASCE Quimby & Associates Views 779 Downloads 75 File size. The roof pressure in the direction of the wind is then multiplied by the projected height and you get a force in pounds per linear foot on the diaphragm. ASCE 7-05 Seismic Provisions A Beginners Guide to ASCE 7-05 Dr. Read the latest technologies presented at key conferences around the world. State-of-the-practice information and guidance on today’s engineering methods and technologies. ASCE’s 35 journals cover a wide range of multidisciplinary civil engineering topics.
The same goes for monoslope roofs whether they be leeward or windward slopes (depending on h/L limit). Browse ASCE’s publications content and find the latest civil engineering news. For instance, gable roofs over 10 degrees in slope have a net pressure that acts horizontally over the projected area of the roof.

ASCE 7-10 offers a complete update and reorganization of the wind load provisions, expanding them from one chapter into six to make them more understandable and easier to follow. I'm a little late to this, but I'll try and answer your question.Īs to part 1, yes, roof pressures must be included if they have a net horizontal force in the direction of the wind. Structures-American Society of Civil Engineers 2010 Minimum Design Loads for Buildings and Other Structures, ASCE/SEI 7-10, is a complete revision of ASCE Standard 7-05. : PAGE : DESIGN BY : REVIEW BY : DATE : Wind Analysis for Freestanding Wall & Sign Based on ASCE 7-05 INPUT DATA Exposure.
