Abstract This paper investigates a particular bridge construction technique
which could result in a significant torsional moment. The
structural member under consideration is a prestressed concrete
girder for which no torsional consideration is made.
Torsional shear stresses can be adequately approximated for
an I-shaped girder. Laboratory model tests were performed to
verify an approximate analytical approach for the calculation of a
torsion constant. The laboratory model analysis resulted in moment
rotation curves from which the torsion constant could be obtained.
These tests confirmed the reliability of the approximate analytical
method.
The results of this investigation indicate that, depending on the
sequence of construction, the design shear stress may be in error
as much as 50 percent.
