A number of steel truss aircraft hangars at Corpus Christ Army Depot CCAD are similar to those that have performed poorly during recent hurricanes in other parts of the country. Engineering analysis of such structures currently in use can identify structural vulnerabilities, and retrofit schemes may be developed to reduce or eliminate these vulnerabilities to severe wind loads. The objective of this work was to evaluate the structural adequacy of four steel truss aircraft hangars at CCAD by conducting structural analyses using the most recent building code guidelines. State-of-the-art data on the behavior of steel structures under dynamic loads were utilized. The current conditions of CCAD aircraft hangars 43, 44, 45, and 47 were evaluated. Structural deficiencies and overstressed members and joints were identified, and retrofit methods to meet the requirements of current codes were developed. Exhaustive data from the engineering analyses are included, and specific recommendations for retrofit are presented.
