DYNAMIC RESPONSE OF CONTINUOUS BEAM ELEVATED GUIDEWAYS. VOLUME I - ANALYSIS

The report describes a Train-Elevated Guideway Interaction (TEGI-2) program. TEGI-2 considers a two-vehicle train traveling at constant velocity over a series of uniform, simply-supported, continuous span bridges. A technique for considering nonuniform guideway beams is developed and discussed. The equations governing the train and guideway responses are numerically integrated from arbitrary initial conditions. The bridges can have initial camber or roadway roughness conditions. As part of the program formulations, the dynamic response of a semi-infinite uniform and periodically supported beam load by end moments is derived. The program calculates motion parameter, wheel loads, and bending moments in the spans as a function of time. Maximum values of these quantities are also determined. As options, the program can consider a one-car train or a single spring mass damper system moving across the bridges. A sample case is run with the program developed using the same vehicle parameters as those for the sample case presented in TRW Systems Group Report, 'Train Elevated Guideway Interactions' (PB-190 635) for the simply-supported spans. It is shown that even with a reduced beam cross section, the response is improved. (Author)
