Eurocode 1

Eurocode 1, Actions on structures, contains within its 10 parts (see table below) all the information required by the designer to assess the individual actions on a structure. It is generally self-explanatory and the actions to be used in the UK (as advised in the UK NAs) are typically the same as those in the old British Standards (BS 6399: Loading for buildings and BS 648: Schedule of weights of building materials). The most notable exception is the bulk density of reinforced concrete, which was increased to 25 kN/m³.
