摘要: Army Regulation 420.70 requires the inspection of trusses, roof framing, and other structural items every 2 to 5 years (AR 420-70, par 3.21, app C). Building 8 at Corpus Christi Army Depot (CCAD), Texas, is an aircraft hangar/shop/office complex of timber construction. The roof trusses in Building 8 were inspected the U.S. Army Construction Engineering Research Laboratories (CERL) and the results were reported. The objectives of this study were to perform a complete, detailed structural evaluation of wood trusses and other support members (i.e., roof deck, beams/purlins, columns, etc.) of selected areas A, B, C, and D in Building 8 and to develop recommendations for appropriate retrofit schemes that will bring the structure into compliance with the latest requirements of the National Design Specification (NDS AF and PA 1997) and ANSI/ASCE 7-93, 'Minimum Design Loads for Buildings and Other Structures.' Although the findings of this study pertain specifically to Building 8 at Corpus Christi Army Depot, this report may be helpful to other Army installations for consideration as a case study when it is necessary to conduct periodic facility inspections IAW AR 420-70.
