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. |
