Pseudo-static test and numerical study of beam-column joints with novel replaceable energy-dissipating shear disc

Key Points

• Improved energy absorption is achieved through the novel shear disc design, enhancing structural integrity during loading.
• The maximum energy dissipation was recorded at 35 kN, demonstrating the effectiveness of the shear disc in beam-column joints.
• Analysis conducted through pseudo-static testing and numerical simulations validates the performance of the energy-dissipating mechanism.
• supports the use of replaceable shear discs; further research may explore practical implementations.
