RE: Definition of "Service" Loads

[Subject Prev][Subject Next][Thread Prev][Thread Next]
AISC calls it "Allowable Strength", but ASCE 7-10 still refers to "Allowable 
 Stress", as do some material codes -- masonry, for instance.  But they use 
 the same ASD (pick your meaning for the "S") load combinations.  Just more 
 mud in the water.

That would actually be . factored downward for Allowable "Strength"
combinations. It just looks like Allowable Stress concepts.
