Re: Definition of "Service" Loads

The way the ASCE 7 and
other documents deal with loads is probably best understood if you're a
statistician and know how to think about mean times between occurrence,
etc.  It is arguable that there is now
such thing as a service load for wind or seismic and probably some other 
things like some hydrostatic or fluid loads.  Especially
for wind loads after seeing what the ASCE did with wind loads in this last 
code cycle.

It does start to get a little muddy, though, when you consider wind and
seismic.  These loads used to be calculated at the "service" level, and then 
 factored upward for LRFD combinations.  Now, they're calculated at the
ultimate level and factored downward for allowable stress combinations.

I have never heard or seen any publication, software, etc, that defined
"service load" as anything other than "loads that occur at the service level."
