DYNAMIC RESPONSE OF PLATES DUE TO MOVING VEHICLES USING FINITE STRIP METHOD

摘要

Dynamic response of beam-like structures to moving vehicles has been extensive-ly studied. However, the study on dynamic response of plates to moving vehicles has so farreceived but scant attention. A plate-vehicle strip for simulating the interaction between arectangular plate and moving vehicles was described. For the portion of strips that are in di-rect contact with the moving vehicles, the plate-vehicle strips were employed. Conventionalplate finite strips were used to model the portion of strips that are not directly under the ac-tion of moving vehicles. In the analysis, each moving vehicle is idealized as a one-foot dy-namic system with the unsprung mass and sprund mass interconnected by a spring and adashpot. The numerical results obtained from the proposed method agree well with availableresults.
