ABSTRACT
The use of refined element formulations for the modeling of flexural behavior of reinforced concrete columns allows for the evaluation and comparison of different indices used to quantify flexurally induced damage. The results of such a case study are presented considering biaxial monotonic and cyclic excitations. Such spatial excitations are known to induce increased amounts of damage compared to uniaxial response. Indices considered include conventionally used displacement ductilities as well as the absorbed hysteretic energy, both along the member and across the critical section.
