Thank you, Ron. I'll look out for that announcement. Does anyone have an opinion either way about the IBC vs ASCE 7 approach to service wind? Using a fixed factor is simpler, but ASCE's MRI method ties the drift check to more tangible performace objectives. -- Christian Parker P.E., M.ASCE...
Hi Huajie, Have you considered section 29.4.2.3? I recognize that a house is typically not a circular tank but perhaps you'd find some useful guidance. The notion of interpolation based on the clearance is probably something you can adapt/apply. There's also a 'bread crumb' in the commentary...
There will of course be wind pressure (both suction and compression) on the first floor level. The reality is, however, that this is never likely to control the design. I doubt that designers of these buildings consider it (but don't know). The live load design for the floor (40 psf),...
Please refer to the new ASCE 7-22, it appears there has been some criteria added for elevated buildings. -- William Rosencutter P.E., M.ASCE Engr Meca Enterprises Inc Broken Arrow OK --
A friend who is designing an elevated beach house asked me a question about the wind load underneath the house. He could not find provisions in ASCE 7. Should he consider wind load under the house? If no, why not? If yes, how? Thanks! #WindandWindLoads -- Huajie (Leo) Liu, PhD....
This message was posted by a user wishing to remain anonymous Hello, Is there an official source of the ASCE wind speed map shapefiles? I would like to have a better source of the shapefiles including the shape of each wind speed lines to plot some figures. Thank you.
Christian, as you note the 0.42 factor in IBC is historic and ties back to ASD design. The ASCE 7 committee has not discussed updating this in IBC, but it could become a topic of discussion for the ASC 7-28 Committee, which will be formed in a few months. Look for a call for volunteers...
Hi Christian, Thanks for your excellent and thoughtful input. I especially enjoyed your style which makes it entertaining to read so thanks for that also! I hadn't considered items in your third paragraph, which offer a great perspective. In fact that's currently the best explanation and...
Hello Keith, I can't answer your question with any authority, but I'll share my thoughts and provide context. You probably already know some of this, just trying to cover all bases. Drawing heavily from two webinars presented by Emily Guglielmo: SEA-MW September 2021 Meeting, and Session 1 of...
