Where a term is used in another Eurocode to which EN 1994-1-1 refers, its definition will be found in that code, not in clause 3.1. The care taken during drafting to avoid defining the same term in more than one code has, generally, been successful. Reference to the definitions in other codes can be helpful. For example, ‘non-linear resistance’ is in EN 1994-1-1, and ‘non-linear analysis’ is in EN 1993-1-1, neither giving the other term. Words like ‘action’ are not found in clause 3.1 because it is defined in EN 1990. It means a load and/or an imposed deformation.
Where there is doubt, the definition in the code being used takes priority. For example, the text of EN 1994-1-1 refers to ‘solid slabs’ and EN 1992-1-1 has a definition ‘slab, solid’. The definition ‘solid composite slab’ in clause 3.1.38 is obviously applicable here.
