STRUCTURAL RESPONSE TO SONIC BOOMS.
ANDREWS ASSOCIATES INC OKLAHOMA CITY OKLA
The report documents and reports on the results of the structural response of some residential structures in the Oklahoma City area during a 39-week testing program consisting of twenty-six weeks of eight daily, controlled sonic booms, followed by thirteen weeks of observation and inspection of the structures to determine the rate of normal deterioration as compared to the rate of deterioration found during the 26-week sonic boom period. The test structures consisted of a total of eleven typical types of residential structures, eight of which were located within five miles of the regular flight path, one of which was located ten miles from the flight path, and the remaining two located about twenty-five miles from the flight path at Norman, Oklahoma which was beyond the sonic boom area. Conclusive evidence of significant damage to the test structures was not produced by this investigation. However, a significant increase in occurrence of minor paint cracking over nail heads and in corners of the wallboard interiors of two of the test structures during the sonic boom period suggests that sonic booms accelerated this rather minor deterioration. No increase occurred in the rate at which paint finish on lath and plaster wall interiors cracked during the sonic boom period.
