Due to the high potential of governing the overall behavior of reinforced concrete structures; particular emphasis should be on the beam-column joints in structural design and detailing. Even though several theoretical frameworks were suggested to simulate complicated behavior of the reinforced concrete components under seismic effects, only a few are validated as feasible and accurate in literature. In this work, a brief introduction to microplane plasticity-damage mechanics formulation of the constitutive model including strength degradation for reinforced concrete components is presented. For parametric studies on beam-column joints to investigate the potential effect of the variation in affecting parameters such as reinforcement size and spacing, a computational simulation framework is proposed. Validation is done through good matching results with an experimental setup selected from the literature. Simulation results and potential for further research are discussed.
