ASCE 7-10 Vs. ASCE 7-05
ASCE 7-10 Vs. ASCE 7-05
(OP)
I had a small building designed using ASCE 7-05. However, the owner asked us to upgrade the design utilizing ASCE 7-10. When the resulting pressures were compared, on this particular building, there is a increase of approximately 10 psf in the pressure for the wall and roof C&C. The pressures were ran using same software for both versions. I have not done hand calculations to verify the results yet.
Does any on have a similar experience?

If I put 160 mph on the note sheet of my building drawings the average non-engineer will get a false sense that their building can handle a hurricane of up to 160 mph. When actuality it is designed more to a sustained wind of 115 mph.
Does anyone have a suggestion of wording or language that can be put on the drawings to demonstrate the sustained or the more realistic design wind speed for a building?

Also, it seems that many people here feel that any increase wind loads is unacceptable, when we still are seeing wind-induced failures in high wind regions, particularly failures starting with cladding and corners or edges of roof structures. Part of the problems have been the hesitation to use locally-appropriate winds which vary from place to place. As the prediction of winds gets better, we should be able to reduce design winds in some places and increase others, without trying to say that place A is like place B, just for the sake of uniformity.

They did a poor job of updating their nomenclature. Notice that ultimate and nominal are interchangeably used in describing the wind speeds in the maps and commentary of the ASCE 7-10.
