AD 254: Design Considerations for the Vibration of Floors – Part 2
AD 253 Design considerations for the vibration of floors warned that where vibrations disturb the occupants of a building it is usually excessive accelerations that cause the disturbance. It also warned that having the frequency of the floor above a certain threshold frequency, such as 3Hz, does not necessarily guarantee that the floor will prove satisfactory in service. In addition, AD 253 described the forcing function produced by walking activities and summarised the dynamic behaviour of floor structures. This Advisory Desk article follows on from AD 253 by giving information on acceptable levels of acceleration and explaining how the expected acceleration may be calculated.
