Scope
This standard provides rules for the determination of accidental actions on buildings and other civil engineering works. The following actions are included:
— impact forces from vehicles, rail traffic, ships and helicopters;
— actions due to internal explosions of combustible gases and dust as well as of vapour-air-mixture; and
— actions for tying systems and key members.
In comparison with the previous edition, the following technical modifications have been made:
a) Transferring design strategies for robustness and related rules to EN 1990;
b) providing consistency between text and technical information on impact;
c) limiting the scope of Annex A to rules and actions for tying systems and key members;
d) inserting technical clarifications in Annex C.
The NA gives national choices on Nationally Determined Parameters as described in EN 1991-1-7:202X. Also, UK decisions on the status of informative annexes and inclusion of any NCCI.
