The complicated mechanic behavior of the Y-shape Bridge is studied based on the theory of the elementary beam, and takes account of restrained torsion, distortion angle, distortion warp and shear lag effect at the same time. A thin-walled beam element with 10 freedom degrees of every node is established by increasing freed degree. Meanwhile, authors establish an analytic program and matrix of the element stiffness, and analyze a typical Y-shape Bridge according to method of the space grillage analysis. In addition, this paper compares calculation results of the general girder and the shell model with experiment test.
