Measurements have been made of the responses of twelve different buildings and one cliff to the sonic booms produced during ten supersonic flights by Concorde 002 along the west coast route. Measurements were made of the levels of induced vibration and of any permanent movements of existing defects. The dynamic measurements show that, with the exception of roof structures, the vibration levels were generally similar to those produced by environmental loads. On roof structures, the sonic boom causes vibrations some two to three times those of the normal environment. The static measurements show that slow movements occur in the buildings due to temperature changes but none could be related to the sonic boom. No significant damage was observed at the monitored sites.
