Abstract:

Statistical estimates of breakage probabilities from noise-induced vibration were calculated for susceptible structural elements at five historic sites near the proposed subsonic flight path of the Concorde aircraft. The five sites investigated were Sully Plantation, Chantilly, Va. Dranesville Tavern, Dranesville, Va. Broad Run Bridge and Tollhouse, Loudoun County, Va. Manassas Battlefield Park, Manassas, Va. and St. Georges Church, Hempstead, N. Y. The structural features analyzed included windows, brick chimneys, stone bridge, and a plaster ceiling. The calculated breakage probabilities for these features were generally less than .001 for a year of projected Concorde overflights-- considerably below the failure rate that would be expected just from exposure to the weather. The only exception was the probability of breakage of lites of glass at Sully Plantation which were already cracked and are expected to be replaced. The response probability density function technique, used in previous studies of structural response to aircraft noise, was the method of calculation.
