Abstract: An interspaced calculation model of a concrete box-girder with corrugated steel webs was built by sap2000, and the applicability of FEM was proved according to the comparison between the test value and FEM value of concrete ...

Abstract: To investigate the laws of creep and shrinkage in high-strength, concrete for long-span prestressed continuous box-girder bridge and predict long-term deflection, strain sensors were embedded in the midspan of a box-girder ...
