“…By considering the fact that lateral load-resisting systems should have two characteristics of high stiffness and ductility associated with their resistance to maintain their suitable performance in structures, over the past few years, severe damages to non-ductile connections have drawn the attention of engineers to analyze the behaviour of new buildings based on the seismic codes and construct earthquake-resistant braces (Oh et al 2009;Mazloom et al 2019). Among different types of connections, steel ring, as an energy-dissipater, can efficiently dissipate energy among the structural members of the bracing system.…”

The present study intended to evaluate the dynamic behaviour of steel ring filled with compressive plastic (S.R.P.) or high-performance fibre-reinforced cementitious composites (S.R.C.) situated at the intersection of the braces. High-performance fibre-reinforced cementitious composites and plastic materials, associated with steel ring connection, seem to be helpful to dissipate the energy through braces better. Therefore, in this paper, the behaviour of S.R.C. and S.R.P. connections was analyzed under cyclic loading. Results showed a steady and relatively wide hysteresis curve for both connections, where the tensile ductility factors of S.R.P. and S.R.C. connections were found to be equal to 2.77 and 13.66, respectively. However, in general, the plastic ring, being operated efficiently to delay appearing the inelastic zone in the S.R.P. connection, was proved to outperform the HPFRCC material in the S.R.C. connection. In addition, numerical results revealed that maximum tensile and compressive loads of S.R.P. connection made with ST52 steel ring were found to be 14% and 10.7%, respectively, higher than those of S.R.P. connection made with ST37 steel ring.
