Pretensioned Box Beams: Prestress Transfer and Shear Behavior

1.

2013 ... Alejandro Avendaño [and six others] · Pretensioned concrete box beams have been used in highway bridges for more than half a century. Due to their geometry, they have often been used as a viable alternative to the classic I-shaped girders. Box beams are highly effective in cases where speed of construction is a priority.
