| Abstract: | It introduces a steel-tube concrete girder arch bridge,with 308-meters long.Because the width-to-span is smaller,the stability of arch ribs is the key to bridge safety.Analysis is made on the arch bridge stability,considering the material monlinear and geometry nonlinear in the condition of different wind loads. |

| Keywords: | steal-tube concrete arch bridge stability analysis nonlinear |
