Abstract

The catastrophic collapse of the Twin-towers has further prompted structural engineers to understand and investigate the progressive collapse of multi-story buildings. This paper aims to simulate the response of reinforced concrete (RC) special moment resisting frame (SMRF) assemblies under column-loss scenarios through nonlinear finite element (FE) modeling. Besides the modeling of nonlinear rate dependent material behavior, bond-slip effects at the concrete-to-steel rebar interface have been considered. The FE model was calibrated against a scaled, single-story, two-bay by one-bay, RC SMRF model specimen with reinforcement detailing conforming to ACI 318-11 code. The specimen was tested un..
