| Abstract: | In this paper, a study on dynamic analysis of light-rail-station viaduct under moving vehicles is presented. Moving vehicles are idealized as a number of moving loads. The overhead and multi-stories' light-rail-station viaduct is modeled by the three-dimensional finite element model. A fully computerized approach is used to assemble the equations of the motion of the dynamic system. Then based on these models and applying the time-integration to the dynamic system, the equations of motion are efficiently solved when light rail vehicle passes and the comfort of people who stands on the platform, station hall or the stairs is evaluated. |
