| Abstract: | The paper presents the analysis of stability for a concrete-filled steel tubular arch-bridge which simultaneously takes the geometrical nonlinearity and material nonlinearity into consideration,and the Wuxia Bridge has been proposed by the method.The failure process under the dead load is examined in the study.Finally,the effects of different load distributions and wind loads on the ultimate load-carrying capacity of the bridge are investigated. |
