| Abstract: | In order to study the flexural capacity of partially filled steel box composite beams, the bending tests of three continuous composite beams under the symmetrical load were conducted. On the basis of elastic and plastic mechanics theory, considering the slip between the concrete slab and steel box, based on the existing researches, the calculation formula of the flexural capacity of partially filled steel box composite beam was derived. The calculation results considering the influence of slip are in good agreement with the experimental results. |

| Keywords: | continuous composite beam negative moment area flexural capacity slip effect |
