Abstract

This study investigates the impact of incorporating panel zones into the numerical modelling of reinforced concrete moment-resisting frames (RC MRFs). Eight- and twelve-story RC MRF models were created using OpenSees Software. The effects of panel zone inclusion were analyzed by comparing the results of nonlinear static (cyclic), dynamic, and incremental dynamic analyses. All models employed the Ibarra-Medina-Krawinkler (IMK) degradation model to account for material behaviour. The static analyses revealed minimal differences between models with and without panel zones. However, the influence of panel zones became significant in the dynamic analyses. Fragility curves demonstrated that models incorporating panel zones reached the collapse limit state at lower earthquake intensity levels. Additionally, the nonlinear time-history analysis showed that while panel zone effects were negligible in the linear response range, structures with modelled panel zones exhibited larger displacements upon entering the nonlinear region. These findings highlight the importance of considering panel zones in numerical models, particularly when evaluating the seismic performance of RC MRFs. panel zones play a crucial role in capturing the inelastic response and collapse behaviour of structures under earthquake loading.
