| Abstract: | Taking 1-joint curved continuous steel box girder for ramp of Ningbo Airport Viaduct as an example, and by dint of ANSYS finite element analyzing program, three-dimensional space model is set up to carry out the mechanics analysis of structure in detail. The mechanics analyzing contents include the support reaction, overall deformation and stress of structure, and the partial stress of deck plate. The calculation analyzing result can provide the theoretical basis for the design of this curved box girder. |
