Abstract: The structure form of great water fluctuation framed wharf is complex in inland rivers. In the structure analysis, the updating of the finite element computation model is difficult. The finite element method is used to build the parameterized model. Three-dimensional static analysis on the framed wharf parameterized model in the most unfavorable load conditions is carried out with the static push-over analysis method. The internal forces of the parameterized model and the nonparametric model are calculated under a variety of the most adverse operating conditions, and then the comparison analys is between their results is carried out. Research shows that the two results are similar; the parame terized model is effective and reliable; furthermore, the estab lished parame terized model and the proposed analysis method can be applied in the optimization design of the wharf structure.
