Re: Case 3 Wind Loads

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Joe,

 

    The 75% reduction is applicable only when using Allowable Stress Design method . The loads should acting on only one axis at a time.

The .8WL combination is used in Strength Design Method.

Kind of an elementary question, but this is the first time I have had to deal with this.  ASCE Case 3 wind loads are 75% of the design wind loads acting on both axes at the same time.  Is this 75% of the factored wind load in the load combinations.  For example load combination 3 uses  .8WL.  For Wind load Case 3 would the factored wind load be .75WL or (.8x.75)WL.

 

Thanks,

Joe
