When a reinforced concrete frame is subjected to progressive collapse due to the loss of a structural column, the surrounding elements typically experience a significant overload that may lead to their collapse. The rotational capacity of beams and, consequently, the beam-column connections is a critical factor determining the structural resiliency. Numerical models developed to assess the structural response under a progressive collapse situation must incorporate the beam-column joint response. In this study, a review of the beam-column joint modelling approaches, constitutive models, and the ease of their numerical implementation are presented. Some of these models are utilized to simulate the response of a previously-tested reinforced concrete frame. The calculated structural response parameters are compared to the experimental results, and the accuracy of each constitutive model is discussed.
