Abstract: The rigidities of the slab and stiffening girder were not considered in our previous nonlinear seismic analysis of the Saikai Bridge that is the deck steel arch bridge. Therefore, the model that can evaluate the rigidities of the slab and the stiffening girder correctly is developed in this study. Natural frequencies obtained by the present analysis are compared with our previous results and the experimental results and then validity of the present analysis is confirmed. Nonlinear seismic responses are evaluated and the effect of the nonlinearity of the concrete slab on the responses of the bridge is discussed by using two different nonlinear material models. It is confirmed that it is necessary to use the models of the exact floor slab and material property from the analysis result of the present research.
