Neither negligible nor monotonic

Imposed loads on building floors, beams and roofs, wind,t snow,t traffic

Accidental A

Usually short (unlikely to occur during the design working life)

Significant magnitude

Explosions, impact from vehicles,* seismic* (symbol AE)

*may be variable, tmay be accidental

*may be variable, tmay be accidental

The self-weight of construction works should be calculated from their nominal dimensions and characteristic weight densities. The table below gives values for materials of interest to geotechnical engineers.
