Shear analysis and static load test of a single-box and multicell composite girders with corrugated steel webs: a case study

The shear design of a corrugated steel web box girder is important for structural reliability. At presently, corrugated steel webs bear all shear forces, and the top and bottom plates of concrete bear no shear force. Each steel web has equal force. This design is conservative and uneconomical and may be unsafe sometimes. The shear ratio and transfer efficiency of each corrugated steel web are investigated in this study through numerical analysis. Then, the distribution of shear stress in corrugated steel webs is verified through a static load test. Results show that the shear is shared by the top and bottom concrete plates and corrugated steel webs. Shear ratio presents a close relation with boundary, loading, and section position. The influence of transverse diaphragm to the shear ratio is minimal and this influence demonstrates a certain only effect on the steel web located at the area of the transverse diaphragm.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
