FULL-SCALE TORSION TESTS OF PRESTRESSED CONCRETE I-BEAMS

In modern concrete highway bridges, torsional loadings are created in a variety of loading situations both during construction and during the service life of the structure. Overhanging deck forms cantilevered from edge beams are a primary source of torsional loading during construction of a prestressed beam, cast-in-place deck structure. Torsional loads occur, under traffic, in beams in skewed and curved structures and in other more liberal designs. These requirements have emphasized the need for a better understanding of practical methods for analyzing torsional stresses in prestressed concrete beams. A simple method of analysis and a reliable failure or strength criterion, verified by experimental data, is urgently needed.
