This study investigates the performance of T-stub FREEDAM (Free from Damage) connections augmented with metallic dampers for improved energy dissipation and structural resilience under static and cyclic loading. Twelve beam-column connection specimens incorporating sine and square wave dampers made of steel, brass, and copper were analysed through finite element modelling. The results show that all connections exhibited linear moment-rotation behaviour up to the elastic limit, followed by controlled non-linear deformation. Steel dampers consistently demonstrated the highest ultimate moment capacity and energy dissipation, while brass and copper offered more rigid but slightly lower-performing alternatives. The findings confirm that FREEDAM connections effectively reduce damage while preserving load-bearing capacity, with steel proving to be the most effective material for high-strength applications.
