| Abstract: | Several shear stress theoretical calculation methods of statically indeterminate structures of continuous curved box-girder bridges are discussed in this paper.Comparison of the tested values with the theoretical values of example bridges is done also.By which,general distribution regulations of torque and shear stress of these bridges are discovered.Some suggested referential values for further selection of the calculation model is provided herein. |
