| Abstract: | On the basis of the classic stability thery,which is taking into account geometric nonlinearity and material nonlinearity,a steel truss arch bridge is analyzed by the finite element method software SAP2000.The results indicate that the influence of geometrical nonlinearity is much greater than that of the material nonlinearity,and the material nonlinearity shoudn't be ignored either. |
