This report presents structural design criteria recommendations for theater of operations (T/O) temporary steel highway bridges. The report consists of two volumes: Volume I provides the design criteria, procedures, and material specifications for both Army Facilities Components System (AFCS) bridges and bridges designed by combat engineers; Volume II contains the development and justification for the criteria in Volume I. Evaluation of the existing military design criteria indicated that their use can result in bridges which are potentially unsafe or perform poorly. State-of-the-art methodologies were used to develop static, fatique, and brittle fracture criteria which should result in improved safety and performance for T/O bridges. The recommended criteria are based on modifications to existing criteria for military and permanent nonmilitary bridges. The AFCS bridge criteria are intended for use by engineers in bridge design offices. Use of the criteria by combat engineers to design bridges in the field requires that the recommended criteria be incorporated in existing Army technical and field manuals, When the criteria recommended in this report are used, the material weight for steel stringers in T/O bridges will typically be from 15 to 20 percent less than when permanent bridge criteria are used.
