File name is AAR 5. This program is used to analyze and rate single plate girder railway bridges. All rating is in accordance with the 1969 AREA specifications and is based on member cross section only. The girders may be deck or through and may be ballasted. Seven common types of girder cross-section are considered and each may have cover plates both top and bottom. For rating purposes, eight classes of steel may be specified. If an analysis is required the structure may be considered subject to the basic types of loading used in Program No. 1. For rating purposes, the girders are analyzed for a Cooper E80 load automatically. A maximum of 10 points on the girder can be analyzed or rated. The input required is girder section properties, total uniform dead load for the girder weight, track weight, and other dead loads; various live loads, impact and wind. Output includes a listing of member sections entered and a listing of dead load shears and moments. If the girder is rated, moments, shears and stresses are output for an E80 loading without impact as well as a rating for moment and shear for all sections for train speeds of 40, 30 20 and 10 mph. If the girder is to be analyzed, live load moments, shears and stresses are output without impact. Total values including dead load, live load and impact are also output. It is possible to analyze a girder for shear and moment only, thus reducing the input considerably.
