The algorithm is implemented into an open-source finite element code, is numerically validated using a benchmark problem with simple element removal criteria, and is able to capture the effect of uncertainty in member capacity. Realistic element removal criteria are introduced for mode-dependent gravity load collapse of seismically deficient and retrofitted reinforced concrete (RC) columns. An application is presented using a RC 3-bay, 3-story frame previously tested on a shaking table. In this application, comparison between the computationally predicted and experimentally observed collapse modes is presented giving confidence in the developed analytical formulation.
