Question

25. How do engineer determine the number of cells for concrete box girder bridges?

Answer 1

Engineers determine the number of cells for concrete box girder bridges by considering the depth of concrete box girder bridge.

In a situation where the depth of concrete box girder bridge goes above or exceeds 1/6 or 1/5 of the total bridge width, then they consider a single-cell box girder bridge to be appropriate The primary concern is to assess how deep the concrete girder bridge is when making this decision.
