A reinforced concrete (RC) beam–column ( RCBC ) joint model for the quasi‐static monotonic analysis of cast in situ RC frames is developed and implemented in a finite element analysis program for framed structures. The joint model was developed in the framework of the component method, a method originally developed for steel joints, which consists of three steps: (a) identification of the joint relevant basic components, their interaction, and contribution to overall joint behavior; (b) characterization of the mechanical behavior of each component; and (c) assembling of the components. With regard to the model implementation, the material nonlinear analysis is performed by the fictitious forces method—all the required steps are presented and explained—while the P –Δ method for the geometrical nonlinear analysis of frames is extended to include the beam–column joint model. The paper closes with illustrative and validation examples; while some of these are fully analytical, the others simulate lab‐tested subframes subjected to quasi‐static monotonic loads.
