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 ef
