Abstract The U-shape bridge is one of the favorite designs possessing obvious advantages in lowing construction depth, especially in densely populated areas with an existing geographical layout of the transportation. The present study has developed an analytical solution on the isotropic plate theory basis for analyzing such concrete U-shape bridges. In this solution, the U-shape bridge is structurally regarded as an elastic thin plate with a boundary condition provided by two side girders. All the mechanical performances under different vertical loads including the self-weight can be given in forms of mathematic expressions, which should come handy especially during the preliminary stage of design. After accuracy verification, a parametric study was carried out to better understand and optimize the U-shape bridges in practice. The proposed solution is proved to be a time-saving solution with sufficient accuracy especially compared to the one commonly used based on the beam theory.
