Vibration amplitudes produced in St. David's Cathedral by Concorde Sonic Bangs

Abstract

At St. David's Cathedral, structural vibrations produced by a number of Concorde sonic bangs have been measured and compared with the vibration produced by the structures normal environment. The results show that bang produced amplitudes are not very much greater than the environmental vibration amplitudes. It is unlikely therefore that continued exposure of the Cathedral to sonic bangs would result in appreciably accelerated structural decay.
