With the features of high efficiency, low consumption and good mechanical characteristic, thin-walled composite box beams have been broadly adopted in structural engineering, and its mechanical behavior has became an active research area. As shear lag effect can bring an uneven normal stress distribution on the flanges, it would remarkably affect the strength design of thin-walled beams. This paper focuses on the experimental investigations of shear lag effects in [0o ∕±45o2 ∕ 0o]T laminated box beam under concentrated loads, and test results indicates that the shear lag effect in this composite box beam can be simulated by the two parabola.
