【Abstract】 In the paper, Resisner E ’s method, which is used to analyze the shear lag effect of box beam, is adopted to build the governing equation of U-Shaped beam’s bending. By the above equation, firstly, the following effect factors to shear lag effect, the length of beam, the geometry characteristic of beam’s section and the position of loading etc, are discussed, then, the comparison between the theory results and the finite element results is carried; the result of comparison proves the correctness of this method.更多还原
