ABSTRACT
Gk j = characteristic values of permanent actions <2k ,i = characteristic value of one of the variable actions <2k , i = characteristic values of the other variable actions Ad = design value (specified value) of the accidental actions 70 j = partial safety factors for any permanent action j Y o a ,j as 7q j but for accidental design situations 7q = partial safety factors for any variable action i V'o, 'Pu 2^ combination coefficients to determine the combination, frequent and quasi-permanent
values of variable actions
In expressions [2.7(a)] and [2.7(b)], prestressing shall be introduced where relevant.
