In China, the theory of transverse load distribution is widely used as a practical approximate method of calculation for space structure of girder bridges. This approximate method will lead to some error. So this article will take a five piece box girder continuous bridge as an example,A 3D solid finite element model of this bridge is used to calculate the transverse load distribution with the concentrated force applied on the main-span and side-span separately. The results are compared with bridge loading test data and show that: when calculating the transverse load distribution of the continuous bridge the corresponding equivalent deformation is more precise, while the moment is relatively unsatisfactory. And the side-span precise is more accurate than in the main-span, meanwhile using 3D solid finite element model to analysis the load transverse distribution is practical and accurate according to the comparison of FEM and experiment results. |
