Wind load combination

Wind load combination

Wind load combination

(OP)
Got a question about wind loads and the use in combinations. Its been a while since I have done a wind load design.

For the combinations, it seems that wind loads are always 1.0 in ASCE 7-10

From PCI, they are 1.6. I always use 1.6. That is ASCE 7-5 reference.

Did ASCE 7-10 change the wind loads to be higher, thus a 1.0 can be used?

Feel stupid asking this question.

Yes - the ASCE 7-10 wind loads are "ultimate" loads similar to seismic and thus the 1.6 wind load factor was reduced to 1.0.

in 7-05, for example, in the central US, you'd use a wind speed of 90 mph. Now in 7-10 the speed is 115 mph for a basic risk building.
There is also no longer a wind importance factor as it is built in the multiple wind maps.

Probably to best educate yourself go to the commentaries in 7-10 where they discuss this a bit deeper.
