Combined corrugated steel web

The invention discloses a combined corrugated steel web, and belongs to the technical field of bridge engineering. The combined corrugated steel web comprises a plurality of circulating joints which are sequentially and fixedly connected end to end in the section direction, and each circulating joint comprises a first unit body and a second unit body which are fixedly connected with each other; the first unit body comprises a first wave crest plate, a first wave trough plate, a first left side plate and a first right side plate which are the same in length and thickness, the first wave crest plate is parallel to the first wave trough plate, the first wave crest plate is fixedly connected with the first wave trough plate through the first left side plate, and the first wave crest plate is fixedly connected with the first right side plate; the first left side plate and the first right side plate are splayed. The buckling characteristic value of the combined corrugated steel web is compared with the buckling cha
