Abstract

The transverse stiffness simulation method of assembled small box girder bridge directly affects the internal force distribution of the structure. However, the lattice model of inclined small box girder bridge is seldom studied. In this paper, three box girder bridges with different diagonal angles of 25 m span are taken as the object, and different transverse stiffness simulation methods are used to calculate the natural vibration frequency of the bridges. The results are compared with the measured results. The results show that the beam end stiffness simulation method is most close to the measured results, and the roof section simulation lateral stiffness is much different from the measured results.
