Case Study: Structural Evaluation of Heavy Wood Trusses at Corpus Christi Army Depot, Texas.
Abstract
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 & 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.
