COMPUTER PROGRAM FOR ANALYSIS OF RAILWAY TRUSS BRIDGES

M T Chen, Vikas Garg

Abstract

AAR Bridge Program No. 2, thoroughly updated, calculates maximum bar forces and support reactions of general railway truss bridges under stationary or moving loads. Trusses may be simple supported, continuous over several supports, internally indeterminate or contain counter diagonals. Maximum span length cannot exceed 620 ft for a Standard Cooper E loading, of 1000 ft for other types of moving loads. Truss can have no more than 25 panels and number of panels with counter diagonals cannot exceed 10. There are restrictions on trusses containing counter diagonals. Input required is truss geometry, cross sectional areas, dead loads, live loads. Output includes dead load, live load, AREA impact and total forces in each member and truss reactions.
