 Summary:
 In this paper, computer simulation is controlled by the convergence solutions depending on the type and the number of adopted final element numerical methods (FEM) to application programs SAP2000 and Abaqus 6.13-1 for the purposes of dynamic analyses of the bridge structure. Computer modelling of the structure of the bridge is treated as a 3D design model with 2D finite element (Shell) and a large number of degrees of freedom of movement. To implement dynamic analysis of 3D models is recommended to use finer mesh finite element analysis in relation to the static analysis in order to more precisely describe the forms of oscillation.
