ABSTRACT: The Track Loading Vehicle (TLV) was used to conduct a series of bridge tests. The Big Creek Through Truss Bridge on the Norfolk Southern Railroad in Tennessee was used for thee tests. The theoretical and experimental axial forces in bridge members were compared. The TLC generated influence lines, impact percentages, and resonance curves of member axial forces were determined. The damping ratios in bridge members were also evaluated.
