Abstract:
A direct method is provided for the construction of the ultimate strength domain of reinforced and/or prestressed concrete sections under biaxial bending and axial force. The method, based on the principle of plane sections, only requires the specification of the stress-strain relationships for each component material, the pretension strains, and possibly any other applied distortion. The results may be used for safety checks in new designs and in the rehabilitation of vulnerable or deteriorated structures. A few examples are used to demonstrate the performance of the method and its usefulness in practical applications.
