Research on Unsupported Installation Technology of Corrugated Steel Plate Composite Beams
In the paper,the unsupported installation technology-corrugated steel plate composite beam is proposed based on the Yunyang East Interchange Project.Static load tests are conducted on waveform steel plate composite beams and reinforced concrete beams to carry out comparisons on their stress performance.At the same time,waveform steel plate installation tests are carried out,and the test results show that the theoretical calculation results of waveform steel plate composite beams are in good agreement with the test results;the corrugated steel plate has good working performance with concrete,and the steel shear key can effectively transfer horizontal shear force.The stiffness and strength of the corrugated steel plate can meet the requirements of pouring concrete bridge deck panels;and the waveform steel plate composite beam without support installation technology can meet the construction needs of high piers,curves,and widened bridges.
