| Abstract: | A simplified model is proposed on the basis of the static tests of two types of ribs having the same area of cross section. Stress analyses are carried out with the finite element method. The calculated results show good agreement with the experiment results. The stress behaviour of orthotropic steel bridge decks under elastic phase is systematically discussed. Strain of pavement influenced by the arrangement of structure is emphatically studied. And the deliberate suggestions about the pavement problem are put forword. |
