Abstract Research purposes:Steel-concrete composite box girder with corrugated steel webs has more significant advantages than concrete box girder and straight steel webs concrete composite box girder, and it is an important development direction of the bridge structure. In order to theoretically study its mechanical characteristics，the concept of equivalent thickness of corrugated steel webs bending resistance is proposed，at the same time，the corresponding calculation formulas are obtained.
Research conclusions:(1)The theoretical calculation formula about the percentage of the ultimate flexural capacity that the corrugated steel webs contribute to the box girder is obtained，and the theoretical calculation formula about the percentage of the shearing force that the corrugated steel webs bears in the whole section is also obtained. (2)The ratio of the ultimate flexural capacity of the corrugated steel webs to that of the whole section is calculated to be close to 0， which indicates that the contribution of the corrugated steel web to the ultimate flexural capacity of the whole section is very little so that it could be neglected in the calculation.(3)The ratio of the minimum shearing stress to the maximum shearing stress is calculated to be close to 1，which indicates that the shearing stress is generally uniform along the vertical direction of the corrugated steel web. (4)In the calculation of small span test beams and large span box girder bridges，the ratios of the shearing force of the corrugated steel webs to the total shearing force in the whole section are all less than 85 %，which indicates that the top slab and the bottom slab would share significant shearing force. And at the same time，as the beam depth decreased，the corrugated steel webs bear less percentage of shearing force.(5)This paper can provide a considerable theoretical basis to the construction of box girder bridge with corrugated steel webs，and it is valuable to the research of the same type of bridge.
