| Abstract: | The article describes various analyzing methods of the material non-linearity for the long-span steel-tube concrete arched bridges.Combined with an engineering case,the fiber unit model is used to approach the dual-nonlinearity of geometry and material,especially the influence of material on the stability of arched bridge construction.At the same time,the article quantitatively analyzes the favorable influence of cable wind on the arch rib stability,the setting up of cable wind and the primary tensile force... |
