This paper illustrates the internal force calculation of the railway steel truss girder under the action of lateral load q by using the finite element method for truss segment. Load q is distributed with partition coefficients a1, a2 respectively on the top and bottom longitudinal bracing in conventional way and calculated as planar articulate. When two forces calculated respectively by using the spatial analysis and planar structure method are equal, lateral force distribution coefficient a1, a2 can be obtained. In the end of this paper we take examples of simple through beam of 48m, 64m, 80m, 144m, 192m, continuous through beam of 2×64m,3×64m, dual continuous deck beam of 2×64m and dual simple through beam of 64m and get the partition coefficient of the floor system plane, 0.77, and the other plane is 0.39.
