RETRACTION: W. Ji, K. Luo, and J. Zhang. “Computation of Deflections for PC Box Girder Bridges with Corrugated Steel Webs considering the Effects of Shear Lag and Shear Deformation,” Mathematical Problems in Engineering no. 2020 (2020). https://doi.org/10.1155/2020/4282398.
The above article, published online on 18 July 2020 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the Chief Editor of the journal, Guangming Xie, and John Wiley & Sons Ltd.
The retraction was agreed at the request of the authors, who identified that formulas 2, 11, 12, 13, and 34 in the final published article were incorrectly presented. In addition, the manuscript was found to contain instances of improper bracket placement on pages 5 and 6, which affects the presentation of multiplication and division algorithms. The extent of these errors affects the conclusions of the article and therefore it is being retracted.
The authors and the editorial board approve this retraction.
