Abstract: In order to accurately calculate the transverse distribution coefficient of simply supported beam bridge considering the effect of bridge deck pavement, based on the idea of rigid-jointed beam, a new method for calculating the transverse distribution coefficient was proposed, using the methods in structural mechanics. This method is referred as the modified rigid-jointed beam method, in which the effect of shear slip between concrete bridge deck pavement and the main girder was considered. The transverse distribution coefficient of an actual simply supported T-shaped beam bridge was calculated using the proposed method, the deflection of each main girder and the static response such as the strain of the bridge deck pavement under vehicle load were obtained and compared with experimental results. It is shown that the calculated static response is in good agreement with the measured one, which verifies the accuracy and reliability of proposed modified rigid-jointed beam method.

Key words: bridge engineering, bridge deck pavement, transverse distribution coefficient, shear slip, modified rigid-jointed beam method
