Abstract

At present, the number of lateral connection arrangements in steel plate composite wide beam bridges tends to decrease. In order to study the transverse stress distribution of the bridge, especially load and compare the applicability of the calculation methods for the transverse load distribution coefficient, a 30 m simply supported steel plate composite wide beam bridge was studied. The finite element method and several Chinese and foreign calculation methods were used to calculate the transverse load distribution coefficient, and the thickness of the bridge panel and the size of the steel brace were selected as parameters for comparative analysis. The results show that the transverse load distribution coefficients of the middle beam and the side beam are close to each other. Compared with no lateral connection in the middle span, adding a lateral connection will slightly increase the side beam and reduce the transverse load distribution coefficient of the middle beam. The influence of the thickness of the bridge deck is small. The stiffness of the steel brace needs to be chosen according to the actual situation, rather than a fixed large value. The calculation method given by the rigid connected beam method and AASHTO LRFD code is more reliable.
