| Abstract: | Taking the Wushan Changjiang river bridge as an example,the paper builds the numerical model by using the large finite element software ANSYS,studies the influence of the rise-span ratio parameters on the static,the influence line of the load,the dynamic characteristics and the stability performance through changing the rise-span ratio of the bridge,and puts forward the suggestion on the selection and the design of the rise-span ratio of the concrete-filled steel tube arch bridge. |
