Description of BS 6611:1985 19851.1 This British Standard relates to typical responses of people to the horizontal motion of structures in the frequency range 0,063 to 1 Hz. The recommendations are categorized in accordance with the use of the structures and, in the case of off-shore fixed structures, with the nature of work being carried out. Injury of occupants due to structural vibration is outside the scope of this British Standard. 1.2 Whole-body motion caused by structural vibrations induced by infrequent external environmental forces is considered separately from whole-body motion resulting from structural vibrations caused by frequently occurring force actions. Frequently occurring force actions may arise from external sources, machinery or structure services such as elevators, fans, air conditioners, heating units and plumbing. Both perceptible magnitudes of low-frequency horizontal motion of structures and magnitudes likely to raise minimum adverse comment are included.
Relates to typical responses of people to the horizontal motion of structures in frequency range 0.063 Hz to 1 Hz. Whole body motion caused by structural vibrations induced by infrequent external environmental forces is considered separately from vibrations caused by frequently occurring force action.
