Design Innovation of Large-Span Pre-Stressed Concrete Box Girder Bridge with Corrugated Steel Web

More and more pre-stressed concrete box-girder bridges with corrugated steel web are being realized in the world due to their advantages over the traditional concrete box girder bridges. Characteristics of corrugated steel web technology were introduced briefly in this paper, and its application in Juancheng Yellow River Bridge was also presented. Calculations on the shear buckling strength of corrugated steel web for Juancheng Yellow River Bridge were performed by the use of design code of Japan. Based on the analysis results, a reasonable way to determine the sizes of corrugated steel web is proposed, and it will provide help for designers when performing a design of pre-stressed box girder with corrugated steel web in China.
