| Abstract: | A practical method to solve the elastic governing differential equations for curved multi-girder bridge is presented. Sine series are used to construct the deflection pattern for curved multi-girder bridges. The Galerkin method is used to solve the elastic governing differential equations. Examples show that the method presented in this paper can simplify the elastic governing equations for curved multi-girder bridges, make the solution easier, and improve the precision of computation. This method can be a good reference for curved girder designers. |
