The Analysis and Contrast on the Shear Lag Effect of High-Strength Concrete Thin-Walled Box Continuous Girder

Base on the full test on the shear lag effect of the long flanges and trapezoidal section concrete thin-walled box continuous girder,considering particular characteristics of the concrete thin-walled box girder,if suitable element models and material constitutive laws are chose,the ANSYS program may simulate the fully flexural experimental process of the concrete thin-walled box continuous girder,the deflection and concrete strain distribution of the flanges in different sections and concentrated loads have been analysed.The analysis result is well agree with the experimental result.
