| Abstract: | The determination of the static and seismic response of curved girder bridges is important and difficult. It is therefore the purpose of this paper to present a direct method for evaluating accurately the mode shapes and the final seismic actions of continuous curved girders supported on high piers, with minimum computation time, using the Rayleigh-Ritz method. Application of the method, compared to the matrix technique, is presented in detail. |
