摘要

This report documents an analysis of the effects of high-level acousticenvironments on an Aircraft Maintenance Dock (AMD) designed for the U.S. Air Force by the U.S. Army Corps of Engineers. The analysis includes detailed estimation of the maximum sound levels inside the facility, identification of facility components that are potentially sensitive to high-level vibro-acoustic loads, and a summary of design considerations appropriate for this environment. Several critical components of the AMD were analyzed. Design modifications have been recommended as a result of this analysis for this facility, including increases in ductwork thickness, a new ductwork joint design, and vibration isolation for ductwork, exhaust fans, pipe systems, light fixtures, and wind truss supports. A summary of recommended design practices to minimize potential structural damage or equipment malfunction due to the high vibro-acoustic environments was developed. The type of steel construction to be employed for this facility is not normally exposed to high-intensity vibro-acoustic loading. However, if proper consideration is given to the vibro-acoustic loads specified here for building design and qualifications of internal equipment, the planned use of the facility should not be significantly impaired....
