Abstract:
Arbitrary loading involving not only bending but shear and torsion acting on a concrete cross section cannot be analysed with the necessary accuracy using the existing codes. This applies both to the serviceability and to the ultimate limit state. For this reason, a theory is introduced here which combines the benefits of the classical bending theory (TB) with those of the theory of plane stress. This extension of the classical bending theory (ETB) ensures that all required effects can be analysed with the necessary accuracy, particularly in cases of arbitrary loading including shear and torsion. This will be outlined in the paper. Using this theory, a cross-section of any shape can be handled and various materials, including reinforced and prestressed concrete, can be considered.
