Accidental actions for buildings

(1)P Accidental actions such as impact from construction vehicles, cranes or building equipment (e.g. skip of fresh concrete), local failure of final or temporary supports, etc., which might result in (progressive) collapse of loadbearing structural elements, shall be checked for the relevant limit states.

Note : Measures (inspection on site) should be taken to avoid:

- abnormal concentrations of building equipment and/or building materials on loadbearing structural parts;

- water accumulation (e.g. on steel roofs); such accumulation is mainly possible in the case of a building nearing completion; consequently, this situation is covered by the permanent situation.

(2) Where relevant, the fire exposure should be defined in the project specification.
