DYNAMIC RESPONSE OF CONTINUOUS BEAM ELEVATED GUIDEWAYS. VOLUME II - COMPUTER PROGRAM

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 non-uniform 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 parameters, 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. (Author)
