查询词典 arch bridge

The article finally through analyzing of the Zhejiang YiwuBinwang bridge temperature load, obtained the CFST arch bridge temperature stress rules with the temperature load which is including from top to bottom and from margin to core of arch-rib when the temperature value、 steel pipe wall thickness value and marking value of concrete change. The rule is that the axial force、 bending moment, as well as the shearing force elevates along with the change of temperature increases, so the control section stress which is linear relationship is. The article further proved the change of steel pipe wall thickness and marking value of concrete is not remarkable influence on temperature stress and internal force of arch ribs control section.
