| Abstract: | Using the finite element software "MIDAS" and taking a simplified plate girder bridge as an example,the whole space grillage is modeled in this paper.The static characteristics and dynamic characteristics are analyzed,and the corresponding theorey is reviewd.The comparison test shows that the overall stiffness and carrying capacity of the bridge are improved particulary in terms of safty tolerance. |
