Eurocode notation

[E.OGull]

Hi All,

apologies for the very odd question, but googled a lot and found no answer!

The question is, which words do "G" and "Q" for permanent and variable loads in the Eurocodes come from? I imagine it must be some French or German words.

Kind regards
G

Interesting question. I don’t know but this terminology was used for decades in British Standards long before the conception of Eurocodes, so I doubt its origin is french or german etc.

At a total guess I’d be tempted to say G for Gravity and Q for Quasipermanent (imposed!)? But that’s just me making it up because I have no other answer for you! I’d be interested to hear it anyonr does know the basis.

Incidentally, W is used for Wind and S for Snow. So I doubt the answer is anything more complex than my suggestion above.

I didn't check, but may be from this :

The subject notations are from ISO 3898. I agree with MIStructE_IRE that , the same terminology was used for decades in British Standards long before .

Moreover, in old GERMAN standards, DIN 1045 etc, g or G stands for ( ständige Last, dead load ), p, P stands for ( Verkehrslast, Nutzlast, Live load ) and q stands for ( Gesamtlast ) g + p and Uppercase letter Q stands for ( Querkraft , shear force )
