| Abstract: | The equivalent grid beam method for calculating the second system stresses of orthotropic steel plate bridge deck with trapezoidal longititudal ribs is introduced in this paper. The rigidities of equivalent distribution beams are derived; the structure analysis program of the orthotropic steel plate bridge deck is written; and the second system stresses are analyzed. Furthermore, the results obtained with the equivalent grid beam method are compared to those obtained with the traditional Peklian Esslinger method to verify its reliability. |
