Abstract:Jointless design method is used for an overlong transfer structure. The box section transfer beams are chosen, and the technique of prestressed concrete with bond is used. The integer structure is calculated by SATWE software, and the native forces of transfer beams are checked by the finite element software of ANSYS. The calculating results agree with each other well. The section and collocation of the members, the calculation and design of the transfer beams, and the main construction measures are introduced.
