| Abstract: | The nonlinear finite element method (U.T column-wise method) was used to compute and analyze the geometric non-linear behavior of the concrete-filled steel-tube arch bridge forced by the wind load. Result showed that the geometric non-linear factor must not be neglected when a concrete-filled steel-tube arch bridge is forced by the wind load. |
