| Abstract: | By calculating the shear lag effect of simply-supported box beam loaded by uniform load with finite element method and energy varia- tional method. It is compare to the two calculation results and then analyze the characteristics of shear lag effect on simply-supported beam loaded by uniform load, and then provide the reference frame of precise calculation and further researcher for shear lag effect of simply-supported beam. |
