Permanent action Variable act ion Accidental action- Selft -weight of structures,

fittings and fixed equipment- Prestresses force- Water and soil pressure- Indirect action (e.g.

settlement of supports)

- Imposed floor loads- Snow loads- Wind loads- Indirect action (e.g.

temperature effects)- Actions due to traffic

- Explosions- Fire- Impact from vehicles
