Stress-resultant models for optimal design of reinforced-concrete frames

Abstract : The standard design procedure of reinforced concrete frame structures starts with linear analysis to obtain the corresponding diagrams of stress resultants (bending moment, shear and axial force), followed by the ultimate analysis of each cross section. The main disadvantage of such a design procedure concerns the (highly) statically indeterminate frames, where the failure of each beam or column would not imply the complete failure of the structure, but would lead to a significant stress resultant redistribution with respect to the result obtained by linear analysis. For that reason, we propose the performance based design procedure where the behavior until complete failure of beam-column and frames imposes to consider so-called plastic hinges corresponding to the zones where plasticity and/ or damage localizes. Engineering structures are usually statically indeterminate, so that the total failure of one member would affect the global response of the structure but it would not lead to a complete loss of the structural integrity. Moreover, being capable of describing the softening response of the members of one particular structure can provide an estimate of the residual life of a partially damaged structure. Such a procedure can also help to provide a more detailed crack description, which is needed to make decisions about the maintenance and repairs.
