Cyclic behaviour of steel ring filled with compressive plastic or concrete, installed in the concentric bracing system

摘要: The present study intended to evaluate the dynamic behaviour of steel ring filled with compressive plastic (SRP) or high-performance fibre-reinforced cementitious composites (SRC) 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 SRC and SRP connections was analyzed under cyclic loading. Results showed a steady and relatively wide hysteresis curve for both connections, where the tensile ductility factors of SRP and SRC 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 SRP connection, was proved to outperform the HPFRCC material in the SRC connection.
